I think that would work fine.  you can simply run tcpdump
on the eth interface one of the target machines to test, though.

my experience is that it's naive to assume a vendor has a clue:
_someone_ at the company may, but with big companies like 
IBM/HP/Sun/etc, you're unlikley to find that perfect contact...
