Depending on how are you gonna use it. Just some brainstorming:you can set-up an ,,online'' point for Google users(something similar with DP,but Google oriented). Anyway,the name looks great.
Not much I think... there are so many possibilities to make any other "google*****.com" that you can find your own and still free.
It's not illegal to use something like googlepoint.com. I've registered googlesharedstuff.com without violating any trademark..
