[tor-relays] directory and exit node on same server

[Darrel]

I have been reading the documentation and trying to get up to speed.  Much 
of this is new to me.

My goal is to have a directory server that is only available on my 
local-area network and on the same machine run an exit node available to 
the "onion network". Is this sort of configuration possible?

I am installing a dedicated FreeBSD 9-beta computer at the moment and want 
to run private directory and "public" exit node.
