NOTE already has ICS.

-Try neobuddy's ICS-Stunner v4.3.
Its based on Google's Android (not Samsung's) so everything runs 100% fullspeed. It has the AOKP features so you can customize it to your liking, and it goes great with the Apex Launcher. You can also change DPI and it reverts to Tablet mode. Everything is great except 2 points: there isn't a Super optimized kernel yet (something that can clock higher while using less battery) and S Pen doesn't work.

-Try maxicet's MidNote v3.1
Its based on Samsung's Android by three leaks (chinese, AT&T and Australian). Everything works at ICS smoothness including the S Pen. The only drawbacks are that you don't get the AOKP/CM9 features, you can't revert between phone and tablet modes, the kernel isn't the best available. Oh, and there's no premium suite from Samsung which will be released via official update.

-Future?
When theres a few more leaks or an official update, it will be repackaged to complete the AOSP ROMs and the optimized Samsung MODs.
