In hope for a reply by Dick Swan...

Hello

We are working on a project where we plan to use an RCX machine as some sort of scanner, reading a paper with binary code filled by user with by us pre-defined variables for moving a robot around. The moving robot will be a NXT-build. For the communication between scanner and moving robot we plan to use mindsensors RCX to NXT Communication Adapter (NRLink-Nx). I imagine we will send some sort of messages from the RCX to the NXT, (char by char), which might reply with some sort of handshake that we code. I also imagine we store those variables in an array at the NXT before he start his moving schedule.
Now to the not so precise questions:
Is there any obvious restrictions in the above described principal idea? (Apart from obvious mechanical / sensor restrictions).
We will probably use Robotc for both the RCX and NXT, is there any nice examples of communications somewhere? Like, procedure of messaging.
There is some Robotc example file to download at mindsensors, is it possible to get some guidence of what parts there is crucial to use. Is it included as some sort of header file or simply "wrapped in" the main source code?
Special code for use of adapter should only be necessery at NXT robot?

Thanks in advance
Regards
