how difficult do you think it's going to be to convert from IR to RC? this is
one of the many things i wouldn't mind trying but i honestly hadn't thought of
it before your post. another option is to somehow offset the frequency that the
IR trains work off of to add additional channels. granted the user would need to
have 2 controlers but it would be a huge advantage over only 3 channels.
