I'm not sure you can do this without voiding the agreement with twitter/facebook unfortunately.

I'd suggest the use of Ghostery (works on all major browsers) on the client side, and on the server site, well, you know, not use any like button :>

Heise Online worked out a solution[0]: a two-click Like button. The first click replaces a placeholder with the official Facebook Like button. Facebook objected at first, but only because Heise tried to make their placeholder look official. A quick design change allowed them to keep it.

Yeah that's why I'm not sure. It could be attacked depending on the country I guess, and if you don't use a facebook-like icon, its hard to tell what you're going to like. Debatable I guess

twitter allows custom links/ buttons. These don't require on-loading JavaScript or any calls to their services.
