If you just mean on the same segment; nothing goes wrong.  If you mean on
the same interface on a FreeBSD box, you get a lot of ARP warning
messages.  Then when you post here as to how to turn the warning messages
off (there's a sysctl for it), you get a bunch of people grilling you as
to why you want to do that, even though it's a perfectly legitimate
design.  At least that was my experience.  ;)
