It does require your server to have a lot more of resources, depending on how 
many simultaneous clients are you willing to support.

Remember that if you can have 100 simultaneous connections you will be able to 
support 100 clients only because they won't be disconnecting from the server.

I prefer an event driven approach instead of comet.  That with regular polls 
perform much better to my use cases.  I had an application that used to poll 
for changes every 1 second, and everything was OK (I converted it to an event 
driven approach because we could narrow down updates to changes in specific 
components of the screen so we saved even more connections to the server).
