If you have even one single port open outgoing, all you need is to get
a remote Plan 9/Inferno exporting /net on that port. I did it on port
22 while I was waiting for the import port to be opened.

#on the outside box
aux/listen1 -t 'tcp!*!22' /bin/exportfs

#from the inside
import -A tcp!remote!22 /net

You're using p9p so your mileage may vary... but the basic concept is
sound and allows you to completely avoid the firewall, assuming you
can actually use a remote /net on p9p. If not, well, you should run a
real Plan 9 :)
