Re: Flex & RPG

I guess in the end I am mostly interested in business apps (ie forms with
business data back and forth from the data base), so I would agree that
streaming audio isn't really a good thing to measure.  Though it does bring
up an interesting point - the reason it takes so much to render video or
audio in Flash is because they encrypt it in many cases in an effort to
protect the media from pirates I would guess.  In the case of Pandora they
are actually downloading the encrypted stream, then decoding it to an MP4
document in the /tmp/ folder on my Linux machine.  Why not just download the
MP4 document and skip the encryption piece - didn't take too long to find
where they were downloading it to.  Does that make me a hacker? :-)
