[Planetlab-devel] Re: new PLC API

[David E. Eisenstat]

The NM end of the ssh tunnel code is concentrated in the files 
forward_api_calls.c and delegate.py in the NodeManager repository. 
forward_api_calls.c gets compiled into an executable that serves as a 
shell for the ssh tunnel accounts created in delegate.py.
