Well, Gish alone did amazingly well. It won one of the Independent Games Festival grand prizes one year. Their popularity has skyrocketed since then. That's not to mention all the other games they sell now. So I'd say they are doing very well. In terms of the strict thing, I would say not at all. They are very good with letting the developer keep their IP. It seems they stick to selling and marketing, and let the dev keep to making the game. Which is exactly how it should be.
But, and this goes for any publisher, always look at what kind of games they already sell. CL tends to do much less casual games, as that market is overly saturated to begin with. They do more non-conventional titles. I would say definatly talk to them, it coulden't hurt.
However, if you want to have it go anywhere, I would highly recommend you go in with a design doc, and a prototype. Have a full document written up about how the game should work, and have a small prototype outlining some of the game's key features. If you're game is already done, even better. :)
