Hi Gerald!

This looks promising, although a lot of work to do ;-)

Here's what I got when I first compiled:

I could remove the DeprecationWarning when simply removing the � char 
(line 3 in xulender.py), this might be a warning as I'm using python 
version 2.3

The unbound prefix error was due to the prefix "ethereal:" at line 63 
and the following ones in ethereal-main.xul. I simply removed them, and 
I could compile.
I just don't know if that was the right thing to do.

After fixing this, I could compile and got a wethereal.exe. I could open 
the about and file open dialogs, but when I tried to load a file, it 
failed somewhere in the epan code,
regardless of which file I choosed.
