Sounds like "iSight Live!", an FxFactory plug-in for FCP/Motion.

So it must be _possible_ to do an FxPlug that takes in an external
video
signal.
Oh yes, it's definitely possible. The questions are - 1) is this
useful for users and 2) is there a better way to do it?
For "iSight Live!", it's not clear to me from the web page what the
purpose is. It says you can pick a color off of a client's brochure.
That's certainly useful, but you wouldn't really be using it in a
sequence or Motion project that you're going to render later on. You
might be able to use it for live VJ stuff with Motion. My point being
that to use it as a capture device, you'd need to have the generator
sometimes displaying the signal live, and other times playing back
what it previously captured. It would be easier for users if you just
made a QuickTime component which captured the video data to disk as a
QuickTime file and let them edit it however they want in whatever
application they want later on. That is, unless there's some other
thing you're trying to do that hasn't been explained.
So to summarize: It is possible, but it's not recommended.
