Need pointers on building stand-alone application plug-in that calls Python scripts.

[Read Roberts]

I would like to build  a plug-in for the Adobe InDesign program, that 
uses Python but does not require the user to have previously 
installed Python.

I suspect that an efficient path to this ideal is use the 'freeze' 
tool to build a directory of all the objects I need to run the Python 
scripts. and them modify the C code main program entry points to 
convert the executable to a dynamically loadable library, for both 
Mac OS X and Windows 2000.

Can anyone confirm that this is indeed a reasonable approach, or 
suggest a better development path to the product?
