i really don't understand what the argument is about. if all one needs is smoothed fonts on plan9 then short of exposing a fontsrv's file descriptor somewhere on the public net, we can get "fontsrv for plan9" in one easy step:
$ for i in `9p ls font/Zapfino/12a`; do 9p read font/Zapfino/12a/$i > /tmp/font/$i; echo $i; done; $ acme -f /tmp/font/font loop for all fonts we're interested in.
