Subject Re: [PROPOSAL] Flex for Apache Incubator
Date Wed, 21 Dec 2011 00:46:39 GMT
Thanks a lot, Alex.

I just wanted to get a better understanding of how Apache Flex relates
to Flash Player, Tamarin, Adobe AIR, and your responses really helped
me to get a better understanding of the proposal. All I have
heard/read so far sounds very promising. I like the direction Adobe is
taking with the proposal.
