The problem comes up when you try to host the IronPython engine inside any AppDomain other than the DefaultDomain (as I assume you are doing in AutoCAD, we are doing in LabVIEW and as you would find if you tried ASP.NET). The most common way to create a new AppDomain is with null evidence, because you typically rely on the assembly evidence to handle CAS (as you were trying to do with caspol). Even if you do domain.Evidence when creating your own AppDomain, you still get null - there is something about the DefaultDomain that we are not inheriting.
If you read the docs on DefineDynamicAssembly(), you'll see that only fully trusted callers can supply evidence - and somehow we are not...I'm still trying to figure out what's the special invocation to make it work with the evidence, but so far I've only found one way - create your own evidence when creating your AppDomain and add MyComputer as the Zone. I'm not about to ship that code as it seems to break just about every part of CAS, but it is a clue...
