Whatever happened to MC2 anyway? We currently use a fork of MC, no? In the longer term, does MC2 make more sense? Can we merge the changes from Trunk (e.g. atomic loading) into MC2? How much work would that be?
I regularly hear people asking for feature x and see replies to the effect "MC2 does that." So it seems like it meets some wants, if not needs. Are there objections to MC2, is MC2 just not well baked, or is it just a lot of work that no one is excited about doing?
If the problem is the latter, maybe someone who knows a bit about MC with a spot of time should ask ESUG for a grant.
I tried doing a port of MC from trunk to Cuis one night, and I learned two things:
- MC is complex (I expected this)
- I don't understand MC well enough to port it yet. Got the UI and networking going but that was as far as I could go without hitting the low limit of my understanding
