Wow, great!

To implement the whole thing with EvenListeners is a good idea in my
eyes. It would keep the whole thing simple and tell the client that
something happend and the client can act is needed.

I dont know if you´re asking me or someone different.
However, I think its really great!

This would enable JS-developers to ship arround one of the biggest
problems when using javascript for interactive-multiuser-stuff: The
bidirectional communication.

Of couse, the current implementation isnt really bidirectional, because
it forces the client to act, when the server tells the client to do
something, but it keeps things simple and allows the js-programmer to do
the same thing like with "real" bidirectional communication.

Really great, dynapi rocks so much!

PS: Is there a efficient way to add html to a dynlayer, instead of:
strold = dynLayer.getHTML();
dynLayer.setHTML(strold+strnew);

PS2: How hard would it eventuelle be to port Dynapi-3 to Konqueror3?
How long did it take to port dynapi to opera7?
However I use Mozzi, I think its more important to support Konqueror
than NS4, because the number us NS4-users decreases every day.
With Safari + Konqueror many users will use the KHTML-engine althought
its not my taste...
