computer geeks. check out new technology i just created.
Real-time updates demo
real-time PUSH for browsers. reduces overhead of HTTP and with that lowers server load and content load times by a significant amount. source code is included.

I'm not quite smart enough to understand what you have done (But I'm interested). I think most current "AJAX" apps use some kind of "long pull" technique -- e.g. they keep a request from the browser open for a long period of time, waiting for something to come down the pipe from the server. This can have a similar effect as a "push", although it is not.
So, does your solution depend on a Flash plugin? I guess I have to read about "Flash TCP Sockets".

yes, but its very inefficient because request just sits there taking up open apache nodes. on top of that there is a very nasty overhead of http which adds sometimes useless headers that you shouldnt even care about in this scenario. with my approach i removed http completely (except for loading initial page of course) but unfortunately it does rely on flash sockets so this wont work on mobile browsers :(
next week i will be implementing secure sockets (either ssl or tls)

by the way, just did benchmark... my server (2.4ghz core 2 duo, 2gb ram, 250gb raid 5 sata, intel 1gbps network card) maxed out with 985,564 concurrent connections sending packets back and forth constantly! memory was as 55%, cpu was at 40% on one core and 70% on second core, and i had to stop because network card maxed out.
in my next release i want to have ability to load-balance and fail-over servers and have ssl sockets for secure connection.
also, i have another project in the making - low-cost highly-available load balancer which will let you load balance and cluster databases (mysql/postgresql/mssql) and web servers (probably based on nginx). its currently in pre-alpha but i do have some working code for database balancing and replication. in actual release i plan on having file server balancing and replication as well. still debating on what exactly i should use as transfer protocol... was thinking nfs.
