The answer to having slow reverse DNS lookups is of course having way for the machines to find each other through DNS. Adding the files to /etc/hosts seems like a perfectly good solution to me. As long as your lan is pretty stable and doesn't change much, this should work fine. Of course you could also run BIND on one of your unix machines. Running DNS internally should fix the problem too, and only require configuration changes in one place.
