Probably.  I think the main problem you'll run into will be the UI, since
the BTreeFolder is going to probably display all its contents without
filtering out PlugIns.  You may have to do some work on that.  Other than
that, though, my guess is that a BTreeFolder mixin would layer nicely over
PlugInContainer.
