I'm in a little different position. I want as many sites as possible to link to my games.

However, I do also want my games to be only hosted by my server, so I use a little bit of PHP to serve up a an ad in my games. The ad itself is just a swf file that contains the code necessary to let my game be played.

I'm sure someone could use a Flash decompiler and take all the code out, but for the most part it works pretty well.

And in the reasonablly near future, I actually plan on paying sites for having my games linked, there will be no reason for anyone to not want to use my games, my way.
