Some of the transformations are pretty straight-forward, but others
are can be more complex. The trouble is the difference isn't really
that apparent at a glance. The simple cases are pretty straight-
forward, and non-technical people (with appropriate review) would be
able to handle them. What I'm scared is somebody getting mired down
in one of the complex cases.

That being said, there appears to be little response to this thread
from people willing to help, so any additional work would be
welcomed. (I'm tempted to ping users@ and troll for folks, but I
don't have the time to review the plethora of patches that may create.)

Hopefully we learned our lesson from the 1.5 release (see the paper
linked to from HACKING). The WC-NG bits that are going into 1.7 are
actually a small subset of what *could* happen. Greg and I have had
several discussions about what could be, after we get the WC-NG
architectural changes in place. The current work is designed to be
"stable" from a backward compat perspective, since we are going to
have to support it for a long while to come.

Go for it. I'm happy to review wc-ng-related patches that come in.
