That's exactly what I was thinking but I didn't know about GEGL!
I could work on this for GSoC. Making it possible to import/export
meta-ops from XML and improve the existing graph editor so a user can
define his own meta-ops :)
Please consider this as an alternative proposal, if the "User Friendly
Plug-in Browser" doesn't sound feasible (at the moment) or not
