Purchasing Penumbra as a gift

[Neuromante]

Hello makers of Penumbra and other non-directly-penumbra-developers-people!

Yesterday I got the Humble Indie Pack and found about the cupon thing. As I like nice offers, I'm about to get the trilogy for the discounted price.

But, oh my! A problen arises: My Paypal account its shaking. Of course, I have friends, and, more acurately, friends with non-shaking paypal accounts. This, together with the fact that I actually have some "retail money", gave me a nice idea.
But, again, a problem arises: In your shop there's no information about "gift-giving", or even "what" I get when I purchase the pack (Or at least, I haven't been able to find it). So, in form of short-non-story-driven questions:

- There's any way to get a friend to buy for me the games with the cupon and give 'em to me as a gift? (Besides him purchasing and giving me the links)
- Do I get, on purchase, a download link "wich will last forever", as those wich I got with the humble pack? (So I can download the games, store 'em in a external hard drive, smash it "accidentaly" with a hammer and then download the games again)

I have a stron feeling those are already answered questions, but I haven't been able to find the answer, so, any answer?
