[Planetlab-devel] error: AddNode failed - hostname already present, or not valid ?

[Larry Peterson]

The alternative is to use geniwrapper, but remove the PLC-specific
pieces, and keep only the interfaces. A challenge, but doable. (We
are also producing WSDL, which you could use as a starting point
for generating your own code.
