Same exact story as the guy above me!
I got a private FTB pack that people in my college can play together on, and I'm including Fastcraft on it in the next update.
BTW, Awesome job on the mod, it is very helpful, and may let a few more people play with us!
If you need to get ahold of me at all, hangouts me through Google+ (google.com/+TommyMiller)
Cheers,
Tommy
