The only thing to be careful about is to make sure the 2.0 software will
talk to the RS232 connection.  They may have the drivers wired into the USB
only.  Anyone have a 2.0 set they have tested the RS232 on?

Thanks for pointing this out. My reason for asking Lego Direct about
this (as opposed to trying to get one from other users) actually has
more to do with the possibility that Lego has addressed the main
problem people have with the IR towers: that they shut off after
several seconds of disuse and therefor become useless as a means of
just gathering telemetry from the robots. I'm secretly hoping that the
2.0 towers have a listen-only option that still conserves power but
makes monitoring the robot's movements and actions possible. Since the
existing models don't do this, my hopes rest on the 2.0 towers.
As for the software compatibility issues themselves, I hadn't really
considered them to be an issue since USB communications are handled by
the USB driver not by Lego software. Given that both USB and RS232C
are serial in nature, I don't see why this would require Lego to
change the data formats. Addressing information for USB devices, as
well as handshaking are handled by the driver (ideally) so I believe
it should be transparent to a given application. What I do see as a
potential problem is that if Lego has changed the design of the IR
tower (which they obviously would have) they are not likely to have
made two interface designs so I suspect that if they have removed the
limitations from the IR tower, I'll end up out of luck anyway.
