Ugh.  I'd highly recommend against it.  You're entering a world of pain ...

We want to try to kill etree as soon as we can; i'm almost inclined to just drop in gtktreeview ASAP, and then hope that this just forces the gtk+ maintainers to fix the performance issues.

Apart from multiline select scaling miserably, if you use a custom model, and not the weird supplied models the performance isn't that much worse than etable.

As opposed to?  Evolution?  I dont see the files changing license, but I also don't see it being usable outside of the tree, if we can help it.
