Sure is, and I'd bet many people would be interested in seeing
Dave's presentation as well. :)

That's right. The GROUP part type was added for two main
reasons: One was to begin to have some re-usability of components
in edje (at the edje/edc level at least), and the other was to allow
one to build trees of edje groups via the edje/edc syntax.
Brian (rephorm) and I had discussed several other enhancements
to edje to allow for such things as: a 'styling' mechanism that would
allow for changing part description attribute values, a notation for
such things as 'extending' or 'overriding' referenced group defs,
allowing for group parts to be referenced from group defs in other
files, more scripting power, and other things.
But we both got sidetracked with other things and never had
a chance to follow up this. :(
