So, I just happened to be playing around with this a bit.  I integrated 
some classpath stuff and fixed their bugs.  I also added a configure 
option to use dnsjava (http://www.xbill.org/dnsjava) so the whole VM 
wouldn't block while calling gethostbyname()/etc...  I can clean it up a 
bit, wire up caching for dnsjava and send it out.
