certainly work for 2.4.0, but I don't know if they are *all* backward=20
compatable. If I can I'll snoop through the various patches. I'm=20
guessing you could apply that part of SteveA's patches that deal with=20
the __init__ method of DataSkin and apply that to 0.4.3p2 and it would=20=

work.. but it's just a guess at this point.
