I managed to make the processes start with this code:

ProcessHelper: http://pastie.org/private/dlkytj8rbigs8ixwtg

TokenImpersonationContext: http://pastie.org/private/nu3pvpghoea6pwwlvjuq

The service calls the StartAsUserFromService method, and the process calls the StartAsUserFromApplication method to start its successor.

I'm using LogonType.Batch in the LogonUser call because the process needs to talk to another WCF service and needs to authenticate. LogonType.Network and LogonType.NetworkClearText could be used, but caused permission issues in the Net.Tcp Port Sharing Service with the Worker user account.
