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.

Thanks,
Om
