Looks like the tech-cats have been playing games in Google's Sandbox.

Developer Tony Ruscoe went mucking in the www.sandbox.google.com subdomain, and stumbled across a number of developing services, among them:

Google Events,
Google Real Estate Search

and a few that are a bit less obvious:

Google Guess,
cf,
gmt and voice.

I imagine voice is VoIP-realated..........

but what could Google Guess possibly be: a joint jeans venture?

Go for urself!
