I did just that last week for my home network.
The reasons being twofold:  1.  copying and maintaining
host tables became a chore with each new machine 2.  dns requests
were killing us time-wise, we needed a cache

As long as your server isn't already authoritative for any
'real' zones you shouldn't have too many problems.  

I simply installed 8.1.x bind on one of the fileservers,
built the forward and reverse zone files and set it loose.
The performance has improved drastically, and i no longer
need to maintain /etc/hosts .    One difference with my
setup is that our internet connected machine *does* gateway
for the internal net with ipmasq ..

If you feel the need to run bind on your internet box,
you could turn off access to the external interface  or restrict
access to the internal zones  for good
measure if you're worried about any confusion..




hope this helps,
