I've been testing out some other people's Google gadgets to try and get an idea of common practices I can use in my own gadgets I'm playing with.

I see tonight that many Google gadgets have a 234x60 text ad at the bottom of them!

Wouldn't you think these would be against TOS?

I know, when looked at directly, these can just look like a small web page. But these aren't designed to be looked at directly, they're being viewed in a window as part of another application (iGoogle or embedded on someone else's web page). Wouldn't this be against the TOS that says Adsense can't be popped-up or embedded in other applications?
