Hi Matt,

I also think this is very cool....but I must say that for the average  
windows user they are terrified of the commandline, so I am hesitant  
to recommend more reliance on the commandline for that reason, after  
teaching first-time users commandline use for many years.

That said, this would be a nice thing to run in the backend that the  
user doesn't notice (e.g. user presses "update all packages" button  
and the installer executes something lke "o4w-apt update").  This in  
fact would work with any installer environment, including Nullsoft.   
Food for thought.
