The last time we had a bat in the house, I used a flashlight and a leather glove and did a relocation. But then again I was home alone at the time. In your position Nate the bats fitness would have probably been reduced to zero.
Rabies in bats is way overhyped. Would be much more worried about skunks and raccoons.
Dinny, check out the WeGotServed website. They have a nice (but not free guide) to the built-in Lion server. It probably does most, if not all, of what you need. I'm sure ML server will be pretty similar.
Yep, I only have Lion on the air. Everything else is Snow Leopard. I'll probably upgrade the air and keep everything else the same. Now for the real decision. New iPad 3 or new Air.
