Well, if aptitude uses it and if they want to benefit of network
caches, they will need it by definition :)
Anyhow, my point was mostly about reusal. *IF* there is a proxy
solution that come with a sane default configuration and can be used
by aptitude acing as a client, I think it would be worth to
investigate. But given that I'm just suggesting and haven't actually
done the homework of considering all available solution, you can
safely ignore me :)

Ah, I didn't get that from your first post: a proxy-enabled network
library, is that it? That would be very reasonable, even though I
don't know have any such library right on top of my head.

True. The drawbacks are that if you want it to be transparent for the
user you have to be a bit careful. A cache can grow and I (as a user)
like to know that I can throw it away when I want without breaking the
depending application. That works for most of the stuff living under
/var/cache/. So, if you want to go that way, I suggest to use a
.sqlite file there, ensuring that the user can delete it whenever she
wants.
Cheers.
