Neat, thanks!

I recently committed a version that uses a simplified version of the C
program[*] but doesn't need to go through /srv.

Your version of -srv mode is certainly better though!

An interesting idea would be to combine both of your modes: proxy.go
would always create an unique name for /srv, and then print it to
stdout.  A wrapper shell script could then do

proxy | while read i; do
	(
		mount -b $i /dev
		$*
	) &
done

(Apologies for the unixisms; I couldn't figure out how to read in like
that in rc.)

[*]: None of that threaded copying monkey business I had before; it's
just passed the 9P connection as fd 0 and then calls mount(0, "/dev").
