Matt,

You are correct JSON would be much easier to deal with than xml.  That
takes care of several of the problems.

Now it really just comes down to the file transfer from one server to
the other and a verification of some sort that the file transfer was
not corrupt.  Is there a python module that takes care of file
downloads and verification?

Thanks,

Steve
