I stole/scavenge my son rc car attached the remote to the pc parallel port with a pnp transistor,I put an IP-CAM on it ,and controlled the all thing with a C# application.
We want your controls to be on the frontpage of LMR, together with the streamed video!
if you'd ever consider creating and offering this kind of global fun in your house, please let me know :)
Neat project! POV in an RC car seems like a really great idea. If you wanted to add a head-mounted display (possibly with pan/tilt servo controls), I've seen at least one video where a Virtual Reality headset was combined with a tilt/pan camera, so that the camera followed head movement. There's some chatter on an RC forum about this type of thing too (http://www.rcgroups.com/forums/showthread.php?p=13846108), FYI.
I once found a youtube video of the head-mounted camera on an RC car, the following links are similar:

Pan/tilt looks really neat!
