you will have to raise the media awareness, not everyone is so "geek" like us here and wants to "play" with his hardware.
you should try to get in touch with the standards, for example gizmodo, engadget, lifehacker and any other "big" site
which has something to do with jailbreaking and such things.
BEST thing which could happen would be Samsung suing you for closing down

I for my self got here by searching on google for ways to extend or hack my tv`s functions.
actually i think i searched for "firmware hack" or "custom firmware" where i found smartsmurfs thread on another forum with his AR fix
(till erdem founded this one on sf)
i would also suggest, if someone really talented and bored, could build a nice GUI for the Firmware patching process.
This tool could be submitted to some software review sites, and as you don`t distribute Copyrighted Code there should not be any legal issues.
I think you get the point
