Thank you!  I was going to follow Chris McDonough's suggestion and add
something to the Wiki about this but your solution is just perfect.
Of course I have a couple of questions since I couldn't find any
mention of this in the Wiki:

Does this work for any module or just a semi-safe subset?

How are submodules handled?  Just put the full path in the
ModuleSecurityInfo call?  Can you grant permissions for all children
of a parent module (scary!)?
