I meant 4, not 3.

Subject: RE: Lego Cam
There are 3 basic options:
1) A wireless USB adapter of some type (RF/IR)
2) Hack the cam so that data between the video chip and USB controller
becomes wireless
3) Build a video driver package for various existing wireless cams to
bluff the VC software
4) Create a replacement for VC that will allow for other types of video
input
The first option is possible. Let's throw IR out the window because it would
interfere with RCX-to-other communications. The RF components capable of
transmitting a bidirectional USB signal are expensive. Half a year ago I found
a company that had a development kit available for creating wireless USB
devices. They wanted around $800 for it.
While the 2nd option is possibly cheaper, it would involve tearing apart the
camera, redesigning a circuit, etc. Such an endeavor is probably too
impractical. I doubt anyone could hack a cam for less than what an X10 costs,
which is already wireless.
I favor 3 and 4 almost on an equal level (leaning more towards 4, though). Both
require programming skills over mechanical skills, which would make the solution
more "user friendly" for the masses.
A special video driver would allow those comfortable in the original programming
environments to participate in wireless video activities. The third-party
replacement for VC could cater to the more technical crowd and could even open
up areas like stereo vision or break the "8 region" barrier.

Eeer... how about the bandwidth?
Video signals might require several megabits per second.
Any experiences are welcome.
