*laugh* - nah, I just don't know any better!!

What I did find was:

They don't make it easy. ;-)

compiler.misc.set_filename("test", expr)
g = compiler.pycodegen.ModuleCodeGenerator(expr)
code_object = g.getCode()

Actually generating bytecode files is slightly more involved, but 
there's a tool called libxml2macro in libxml2dom which has the magic 
incantations. Right now, I can't remember where I looked to find all 
this out.

Thanks Neal!
