Would you really want that?  I thought we were pursuing this as a tool 
for a virtual hackathon - wouldn't you rather a better editor?  I'd 
think a jEdit or Eclipse would make for easier implementation _and_ be a 
more useful environment.

Been reading it.  Not yet digested... :)

I just finished the section describing the star architecture of Jupiter 
which drastically simplified things.  I also wonder if a sort of "row 
level locking" (well, actually line-level-locking) wouldn't do even 
more.  I have the disadvantage of not having ever seen/used SubEthaEdit 
-- is it really that useful to be able to have different people editing 
the same line simultaneously?

I think that would be monumentally harder and not any more useful than 
an existing editor which already has a Memento type of architecture 
(which designMode and friends may but don't expose do they?)

The last thing I need is something else to play with, but I'm 
interested.  I don't suppose SubEthaEdit is coming out with support for 
other platforms?
