I think BP's right click app is kewl. I was conducting errrr... market research and right clicked a link on his site and got the dialer thingy.
Although I think it's kewl, I doubt if it's very effective since it's not the "expected result". I'd buffer it with something similar to the "expected result". Other sites do the same thing but pop a little vertical menu with sponsors (close to the "expected result").
Hopefully you're pickin' up what I'm layin' down.
Peace and hair grease.
