Well... no - with a sane routing configuration that shouldn't be much of
a problem. I have a 192.168.0 network at home and have no problems
accessing my freerunner without changing IPs.

Actually in that case I would avoid all powers of two. A higher prime
number, like 97, might be a good choice...

But eventually someone is always going to get into trouble, so maybe the
better route would be to clearly explain how to avoid routing
misconfiguration and how to change the default IP (which is done in
/etc/network/interfaces fyi).
