Nice work! That app look sleek!

Also if you look at Aptitude script over at xbmc-addons you could get an idea and code on how to integrate it with xbmc scripting.

Basically it does the following,

• fork of a process which writes it´s progress to a temporary file
  
• XBMC Script reads the progress and show it in a ProcessDialog
  
• When update progress is done, script exits.
  

This is not the most beautifully integrated solution perhaps, but it works
Also I´m unsure if threads are native to XBMC scripting or if we leverage the Linux OS for that, a real scripter would have to verify that.

Cheers,
Tobias.
