Using eggs or py2exe to distribute apps

[Marcus]

Hi,

I'm to the stage where I need to deploy the app I built with wxPython. 
I've been able to successfully build it w/py2exe into a binary (about 
10MB size in total).

What I'd like to do is create an automatic updater, so that I can have 
users download updated versions of my *application code* without having 
to have them redownload everything (the interpreter, etc) via a complete 
redownload (I want to package some things as "components").

Eggs seem like an ideal solution, but I haven't had any luck using them 
in conjunction with py2exe.

It would seem that the most effective solution would be to package a 
python interpreter (with wxPython, etc already included) into the 
distributed app's directory and not use py2exe at all; however, since 
everything would be included in the distribution, it would seem that the 
full python distro would be huge (50MB at least), which defeats the 
purpose of wanting to build the app into "components".

Worst-case scenario would be to have them redownload the 10MB update 
each time, but that's less than ideal, since the audience for my program 
would have more frequent/less substantial updates over time, rather than 
big updates all at once.

Any guidance or suggestions are very much appreciated.
