Nope. As simple as clicking a link with special URL scheme, like `apt+hXXp://archive.canonical.com?package=acroread?dist=feisty?section=commercial`

I'm all for the bundles (which single-app repositories, actually, are!), but I want them to be non-monolithic (i.e. contain multiple separate packages).
I don't care about disk space — if I'm that constrainted with disk space that's probably another story that'll probably never happen to most ordinary users, having terabytes of storage. But I certainly care about bugs, and if libXYZ 1.2 has a critical one, I want my system to be free of that version ASAP.
And I don't care that you've never tested your awesome app with 1.3 — it's better to be possibly unstable than certainly unstable or, far worse, vulnerable.
