Yes, we currently have the better part of 50 or so on a pix 515. The cpu usage is currently sitting at about 15-30%. If you were going to get into the 100 vpn range I'd suggest monitoring the traffic carefully on the 515 and perhaps going up to a 525. It would depend how heavy the traffic load is going to be. Another thing you need to look into is a failover configuration if you're getting into that many hosts and you need any serious degree of reliability.
