Want to learn to mix better?

This is something i know that many do want to do better. but it's hard to get as much practice time as we would like b/c we need the live band and such. So i thought we could try some training sessions of mixing via some old praise sets that we recorded onto 24 tracks. using some software you would be able to eq, add effect, solo, and mix a set. at first this would be through software.

if we get enough interest, we can setup our large mixer at NL and in a room somewhere and try to recreate a studio effect and use our firepods to play back the recordings and you can try a "live" mix.

so what i need to know from you guys is:
1. do you own a mac? what kind?
2. can you spend about a 1.5 hour session with me to install the software and learn to use it?
3. you will need at least 20 GB of free space or an external drive
Please comment.

couple caveats: this is not the same as live mixing. in fact, it's really different. but you can at least begin to learn some of the mechanics - soloing, eq'ing, mixing, listening for instruments, etc... this is reallly post-production but you can at least begin to learn some more...
