Tip jar links for Animes

I'd like to make monetary contributions to the anime industry. It would be great if next to each torrent link there was a paypal link or similar where I could contribute a buck or two when I think an episode or series is really cool. Ideally the money would go to the correct company and it would be noted which episode or series prompted the contribution.

I know its possible to buy DVDs but I don't watch DVDs and I don't want them taking up space in my apt. Why not channel all my money to the anime company rather than waste part of it on physical media manufacture and distribution?
