Thanks for the reply. I'm not a lawyer, but as a ham I have poked around in Parts 2, 15, and 47. The following are just my concerns that might impact your endeavor.
Operating a non-certificated/approved device in the ham bands is one thing - marketing a transmitter of any type is yet another.
If you're going the module route, Part 15.212 puts some pretty stringent limits on what you can do with the module - it has to have the 'unique' antenna connector and must be certified with a particular antenna - "All single or split modular transmitters are approved with an antenna."
Part 15.212 also says that "The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number." That implies that it must have an FCC ID number, which implies some level of certification/authorization.
While it's true that hams can use any equipment in the ham bands and are responsible for their signal purity, those that MARKET such devices have more stringent requirements - Part 15.201(b) says that "... all intentional radiators operating under the provisions of this part shall be certificated by the Commission pursuant to the procedures in subpart J of part 2 of this chapter prior to marketing." I'm not sure how close to 'marketing' your kickstarter campaign is - hopefully the FCC doesn't consider it marketing.
If you go the kit route, the waters are even more murky. For a pretty good review of the state of affairs, check out this article on SparkFun.
Good luck - If I were you I would seriously consider consulting someone that's competent to review your situation and give you advice, whether that be a lawyer or RF engineer, or perhaps one of the Certification labs.
