Nope.  Once downloaded, latency is minimal.  Running on the server makes 
for an annoying experience throughout.  Imagine playing Super Mario Bros 
through server, and your guy only jumps half a second after you press 
the button.  It's preferable to wait half a minute for the game to 
download and run in your browser than playing immediately on the server 
but with a latency that makes the whole thing just crappy.

And?  GMail and Facebook also runs on a server.  Does that means that 
people who use email or Facebook should have to configure servers, learn 
Unix administration and setup services?  No.  All they know is how to 
upload some file and have it appear on their page.

Common man.  That was just an example.  Instead of "audio clip" read "a 
video game" or anything else that requires executing code.
