I've finished my mobile pentest target and will set it up on Sunday afternoons at the Black Lodge for open penetration testing. The box is running VMWare Workstation on Linux and will feature a rotating set of scenarios for your hacking pleasure. The calendar will list the scheduled scenario each week.
This week, I'll have an unpatched Windows 2003 Domain set up and ready to go.
Or work on anything else you want -- the pentest lab is just what I have going on.
