hmm, i initially thought that but broadcast addresses (i think) are
simply another IP that all hosts with a particular subnet listen on in
addition to thier own ip, 

i am uncertian what port halflife broadcast traffic goes to or even if
its tcp or upd , 

but i was thinking if broadcasts are like multicasts then i could simply
route to the host and then iptables filter out any 'misc crap'
