2) I would suggest getting onto the Bitshares forum and start up a TimeShares thread laying out your ideas, vision and details within that community. Like Fuznutts mentioned, getting suggestions and help from the community members and Bitshare Devs will be a HUGE benefit to the Timeshares project.
The atmosphere is MUCH MORE professional at https://bitsharestalk.org than this bitcointalk.org forum.
You'll get some great advice along with well thought out arguments and it'll help shape the project. Not to mention you'll have influential eyes viewing it everyday.
If you do this, be prepared to stay VERY active and involved within that community... again, you won't be talking to idiots over there!!! FUD is pretty much nonexistent.
