Gadget/Widget

I was expirimenting with creating a FCK google gadget. I was a little confused though, since I would have to publish the gadget to google and, while I personally have no intention of using it for commerical use, I think that since google would passively be profiting from its existence It may be a violation of the FCK licensing. Let me know if there is a green light here or if some sort of collaborative effort is in order because I think having an embedded text editor on my homepage would be swell.
