How about an I2C bus, AFAIK an industry standard, low-cost serial,
daisy-chain bus (connect one piece to the next, from there on to the
next etc) on which you can address a large number of devices (input and
output), including displays, keyboards, other RCX units, PCs (via the
parallel port) etc etc...
A standard RS232 connection to the RCX would be useful too. I drained
the 9V battery of the IR tower in one week - I *hate* throwing away
money and binning (in the recycle bin of course, but still) polluting
things like batteries.
A standard IRDA interface would be neat too, so I can talk to the thing
with my Psion Series 5 at 115K2 baud.

Make the batteries an optional add-on in a lego-style brick, in case
you use a power supply. Even better would be a Lithium battery, of
course.
