Yeah, it's dog slow, but it's a wheel I didn't feel like re-inventing,  
and if you run it periodically (like nightly from cron) then it only  
has to download changes, which isn't quite so annoying.

That's a decent approach too, which I may now use instead, since it's  
a better wheel I don't have to re-invent...  :)

Maybe, but it's fairly uncommon for me to go through all this just for  
one app anyway, usually it's setting up development servers, which  
means it's nice to have a full CPAN mirror instead of just the  
dependencies for that one app.
