I appear to still be having problems with Medium Trust.
I've set the ActiveRecord settings as described here
http://nhforge.org/wikis/howtonh/run-in-medium-trust.aspx

Has anyone got any further than this?

Here is the error I'm getting:

 Security Exception
Description: The application attempted to perform an operation not
allowed by the security policy.  To grant this application the
required permission please contact your system administrator or change
the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: That assembly
does not allow partially trusted callers.

Source Error:

An unhandled exception was generated during the execution of the
current web request. Information regarding the origin and location of
the exception can be identified using the exception stack trace below.

Stack Trace:
