I tried something like that some time ago, and if I remember correctly you
can't get the
nameserver this way (can't remember the reason).
You should start orbit-nameserver which then writes its ID to stdout.
Redirect this to a file and let your program read it from the file, so you
can connect to the nameserver.
Then everything should work fine.

Hope this helps
