Just came out for Mac, had a few hours with some friends and really got in to it.
A bit buggy, it is in beta after all, but still worth a good time. Had some disconnect issues even with my friend in the same country, so I've no clue how best to host such a thing across so many borders and timezones. If anyone has any ideas on how best to set up something for the SG community then please post below.
