Read this a while ago, but forgot to comment: Ray Ozzie’s possible prior art for plugins doesn’t surprise me. As someone who has worked a bit on Lotus Notes and Domino (and whose workplace has some serious Notes gods), I went through a phase of continual surprise at the richness and sophistication of Notes’ workflow model (truth be told, it was combined with disgust at its UI excesses). Microsoft could do worse than make Ray Ozzie their new best friend and centerpiece of their appeals claim.

PS. It’s an article of faith with the Notes devs at work that “this new-fangled web thing” is nothing special, Notes Had It First™ anyway. It’s also an article of good natured jest among everyone else that Notes may have had it first, but it was so damned hard to use that you had to take Certified Lotus End-User Training just to comprehend the majesty of it, and end up not using it anyway :-).
