My take on flying houses and vendors:
A crafting profession can create space houses (whatever u want to name them...) and they act like real houses. You find a spot, you use your deed and place the house there (you'd have to account for the Z-axis too, boy that's gonna be fun

) Your house is then at x, y, z coordinates and it is much like a "normal" house. You dock your ship there, you can then enter it, decorate it, place vendors in it, you might want some windows for it too

Etc...
OR:
To put down a space house you need to find an asteroid. You then set your house on that asteroid, wich has coordinates, you can dock there, walk around in it, decorate it, put vendors, etc.
OR²:
You have a house in space, in either fashion as described above, but cannot place vendors in them (because high traffic malls for instance can't dock 50 folks at once...) So you have Vendor-droids, little probe-like space flying devices that orbit around your house! people can access them by directly clicking them (like a vendor terminal or NPC vendor)
As for ships:
We need "neutral" ships, wich are made by a specialised profession (a ship maker prof if you will), wich anyone can buy and use freely, you can mount weapons on that ship, different layers of armor and shields, hyperdrive, etc. All of these drain on your energy bar (kind of like a 4th HAM bar). Firing weapons, raising shields, etc, all this consumes power. You can buy better power genertaors for your ship, and battery packs wich are like emergency stimpacks to boost your energy level for say, 30 seconds during battle...
Your ship can be incapacitated and it can be DB'ed, much like a corpse. If it is incapped, it will take you 1-2 mins to "repair" it until it can fly again, but if it is DB'ed during incap, it will need repairs at a station. A tow ship will "tow" your ship back to the nearest space station where you have bound or not (and same system as for cloning applies, your ship ends up in worse condition if you hadn't bound at the station, and it winds up in "ok" shape if you had bound and paid a clonign fee.)
Faction ships:
Schematics for Faction ships should be obtainaible by ship crafters by buying them with FP. A ship crafter will buy for a one time Fee of say... 8K credits the schematic to produce a Tie-Fighter, or an X-Wing. Bigger ships will require more FPs.
Capital Ships:
Rebel and Imp capital ships will not be made. They will be directly bought with FPs (think of them as faction bases...) An ISD will be in the range of around 100K FP. I think ownership of a capital ship should be given to a Guild, and to it's guild leader, and change owner when the guild changes owner. The guilds shoudl have a common FP pool to buy equipement for the cap ship, such as detachements of Storm troopers, new weapons, armor, upgrades, etc, eventually full squadrons of AI ships to guard the cap ship. A cap ship is a slow moving thing. (It takes 30 minutes for an ISD to go around a planet in one of the original 3 SW movies if I remember correctly..) It CAN go to hperdrive, but only for long trips, and prior to jumping it will need to have called back all of it's outer defenses (Tie fighters, eventually squadrons that landed on planets, etc...) wich will make it vulnerable for a while to attacks... (say 5-10 minutes). After that, it will be vulnerable for another 10-20 mins when it arrives at destination from a hyperspace jump. Only PCs will be able to defend it during that time, until the AI guard can be redeployed...
Asteroid Mining:
Space is filled with riches just waiting to be mined! One system will share the same resources (kind of like one planet has the same res all over it) during one shift. You can scan asteroids and deploy mining appartuses on them (harvesters) to mine them. You could also manually mine them (sampling) if your ship had the required equipement (think survey tools).
Space fighting:
Shoudl we only get enemy ships in space? such as brigands, Factional PvE, etc? I think not. The original trilogy shows us a huge space monster (think of it as the equivalent of a space krayt)! Why not have creatures you can fight in space?! I don't think this should be a problem.
I think this sums up my thoughts on SE for now. remember though that SOE already has most of the basic stuff in writing for the SE! They're not going to start thinking about it a month before starting the SE! I'm sure they already have most of the new professions written out with skill names, skill modifiers, etc...
But things like Capital ships will not be at the original SE release, IMHO, they will be patched in later, like with mounts and vehicles...
All i know is that the SE will be exciting... Too bad we'll have to buy a new box for it tho
