An interesting open source alternative in the social VR space is Phil Rosedale's High Fidelity: https://highfidelity.com/

Oh, and it's already full of furries, so you might as well torch it and start again.
Many of the most prolific creators I knew on SL had some affiliation with the furry fandom. I would take that as a good sign, actually: they tend to be early adopters.

The local sandbox is still laggy crap on a recently-built i7 desktop with a 1-year-old NVidia card, though.
