Yes, but only for output. I done web chat with this technology (I
call it endless connection) long time ago, before AJAX era. It was PHP
script on server-side and javascript on client-side. You need
set_time_limit() to prevent timeout on server so you can't do it in safe
mode. And you need to send periodically something to prevent timeout on
client. Request sent to additional short script who put it to database
or another place. Main script in endless loop checks for new requests,
process it and sends result back to client.
Now here is no reasons to do such things.
