I thought about this solution as well, but I think there are some
1. The jukebox has to remember the type of remote which makes is a
little bit more complicated (not very much) for the rockbox guys.
2. How should the remote know when it is first plugged in? We would need
something like a connect-button on the remote or a remote that
recognizes if it doesn't get any screen updates.
3. How does the jukebox know, if the user changes from LCD-remote to

I agree, but there's one more point:
4. I don't want to have an exact copy of the archos display on my remote
(sometimes perhaps). A small remote (or my planned car stereo solution)
could have a small display with one line only and then I'd like to have
the possibility to decide what I want to have displayed there.

I'm a little bit busy at the moment, but I think we should just try
which solution works best. If we have the hardware working, it won't be
a big problem to adjust the software (rockbox and remote) working the
one or the other way and measure power consumption etc.
