Tkinter, X-windows and ebay

[Bob Greschke]

When you post something on eBay (and other places) you can use a 'browse' 
button on a web page to send a picture file from your hard drive to them for 
inclusion in your listing.  Can the same kind of thing (not the same exact 
thing, of course) be done with a Python/Tkinter program that is running on a 
remote machine (that you logged into to start the program), but that's just 
using your computer's display (with X11 on a Mac, X-whatever on Linux, 
X-Win32 on Windows, etc.)?  I've got an inventory program that runs this way 
and it would be nice if users could create a text file on their machine, but 
then have the program read that file and, for example, update item 
quantities according to information in that file.  Things like that.

Thanks!

Bob
