Sounds great Myrathi!
If you want to have it tested on a server, I have a private server with 75 mods, all cutting edge versions, with roughly 10 people on. We'll be happy to let you on the server to do a real-life test of the SMP version. Shoot me a PM if you're interested. We have TeamSpeak and the Minecraft server is on a 40/40Mbit European fiber connection (this is the only server running on that connection, mind you).
