Sloan/MIT - the folks who sponsered the original education package (ACES) - are paying for a port of ACES to OpenACS 4. It will be called dotLRN - search for that word and you should be able to dig up some older threads about the project.
So in short, it's doable but it's being done. However, if you're interested in helping with other bits and pieces e-mail me. You could help with testing, you might be able to pitch in and help port code that's not been ported yet (though you face a learning curve since you're inexperienced with Tcl), you could help by either writing or reviewing documentation (for instance the install guide we've been mumbling about), etc etc etc.
We're not proud. We'll take your help whether you have 15 minutes a week free to contribute or 150 hours...
