Getting this to work with an eggdrop would be simple enough; and the eggdrop would be able to cope with the bandwidth hog.

Unfortunately I know that the fsock functions have been killing my host otherwise I would give it a go.

vB forums -> eggdrop -> irc

you just write a TCL script on the eggdrop to listen on a certain port, the forums connect to the eggdrop and send the line of information and the eggdrop sends the information to a channel.

vbulletin.tcl
listen 1337 script vbulletinaccept

proc vbulletinaccept {idx} {
 control $idx vbincoming
}

proc vbincoming {idx args} {
 if {[join $args] != "" } {
   putserv "PRIVMSG #vbchan :$args"
 }
 killdcc $idx
}
