Why would you want to use Comet? If you write the swing client yourself you can
open a direct socket to the Erlang server. Is there any good reason
for using comet?
Comet is a mess - it solves a problem that should not exist in the first place.
Using symmetric by-direction sockets is far easier.
If direct sockets is unacceptable - then use http websockets.
Comet is a technology that should become obsolete - the only reason
for using Comet
that I can think of is you have a legacy system that uses Comet.
