I have reformatted the wiki page http://www.eigenlabs.com/wiki/AUs_In_Use/
to turn it into a table, with some additional columns that I think would be useful to everyone: price, eigencompat(ibility). It could still use more formatting, and explanation.
I personally want to use my new Pico for composing, and AUs via MIDI seem to be the easiest way of achieving this in an editable way. What do you think?
Anyway, I hope this helps
