The same thing can happen with Ethernet or
any communications protocol that uses a 
shared wire/medium. However, given the fact
that RS-232 is an extremely well understood
and simple technology, I don't think there
is much risk in using an RS-232 daisy-chained
control bus.

Of course the embedded systems folks
might be able to make a case for I2C or
HP1B or something else that is used in
industrial and laboratory control applications.
