Configuration of RSreporthost

Hi,
having used the most of my day trying to do this - i have to ask.
Is there no way to config this tool to get the same permissions as the vs.net preview?
I have a strong name assembly who read the System.Environment.username - and it won't run in the rsreporthost.
Please help me out here..
I've got it right now...
I had a restart (mentally) and now it works.
For the record, I've added a permissionset and a codegroup in the policy config file - and added permission asserts to the code and it works perfect.
