Bumping this thread. Michael, your note about post-processing metadata into an actionscript class and hence speeding things up without having to use describeType() sounds very interesting. Can you please post more info?
I always wondered about how using descriptType() affects performance. Your results could be enlightening. If we really get such a good performance boost, I am all for adding this as a feature in our new Apache Flex.
