Authentication around the REST services model

Hi,

Does anyone have any experience or would like to share there woes with trying to use PP based rest services ?

As with most REST based scheme authentication is always the challenge, it appears that the PP authentication is forms based but I can't see what service you have to call to get a token or cookie to pass to the rest service to allow you to use it ?

An example call is below

http://server:port/auth/launchjob?_compat=1&_format=json&_protocol=some protocol

The documentation is complete apart from any mention on how to authenticate with the REST service.
