I've got the shareware version and jdoom here at work. I use zdoom at home though with the regged versions. I'd be up for some DM today if your interested, my boss is gone for the day.
I would need to get jdoom..but, I am leaving for work in 20min, and, I don't think my boss would approve of me playing doom on company time, let alone touching his sweet box(p4 3.2ghz, 1gb of ram, for checking email:?)
