I've emailed them and had no response at all, so you were lucky! I'd love to be able to play Unlimited variants like Unlimited 150 online but Redshark seemed a bit basic when I last tried it, can you get pictures for it yet?
If someone could maybe make a Pokemon server for Cockatrice that'd be awesome! It's the best free program to play MtG on and would be fairly easy to adapt to Pokemon (we used to do fine using Apprentice >_<), I'm just not sure exactly how these things work and how you'd go about it :S
