Not that i'm aware of, nothing was made explicit but i don't think so. There is a Beta forum that is open to view for anyone, the game game pools my opinion of it's features every now and then, and there is a internal "feedback" option i've been using to tell them pretty much everything i'm telling you guys now. The Beta is made of about 3-5k people an d you can find gameplay videos on youtube so i don't think there is an NDS in place.
There is your basic EULA, but that is common fare of pretty much any game.
Here is a 37 min video of the Beta made by someone else
And just to illustrate stuff better... for some reason Fraps is the only thing that works
