If this limitation had applied to the rcx, I'd have suggested this. Because you
can control the outputs and read the inputs direct from a pc you could run an
emulation of the rcx firmware running your program on the pc. The rcx would then
behave in the same way as if you had downloaded the program onto it. You would
have course have the transmission delay caused by the IR link. But whether that
was a problem would depend on your application. I suspect the same could be
applied to the NXT.
