If AOP didn't look interesting enough, and it does, the most tremendous value from Max's presentation was the methodology he used to develop his resources. His discussion of using the tools from the Tamarin project is a real eye opener to the lengths one can go to solve Actionscript problems.
AOP looks pretty tasty, too. The ability to create program level Advice handlers seems pretty damn useful. His live examples, unfortunately, are mature on the Java side, but the prospect of doing this, seamlessly in Actionscript, threatens to be a really powerful timesaver.
He reports that he'll have his Actionscript AOP libraries in a few weeks, so it is worthwhile to keep an eye on his blog to check for Loom Actionscript AOP updates.
