Dan,

my first thought is to provide a second invocation mechanism for the 
interpreter. So do not call it as an interpreter from the Add-on but 
simply call a new function that creates the proper context for the 
original interpreter code and executes it. (In other words, the Invoke 
or InvokeEx functions in BON would not be called, but a new function.) 
So it would execute in the transaction of the Add-on and it won't try to 
create its own. Yet it can still function as a regular interpreter when 
it is called from the GME gui.
