This is not in production use. It does not work with IE 5 and has only
been tested with Mozilla and IE 6. It needs few DOM functions, but these
are not easily replaced. It is mainly research for an interesting future
option.

My idea is not to push worload to the client, but to seperate moving
data (to the client side) from static data (to the server side) to get
better page caching. 

Have a look at http://www.music-head.de/ and put something in the cart.
The cart is displayed using images with numbers, while the catalog pages
have a last modified and do not change. This could be done much better
with domtal.

However experience tells me, that client side javascript is best
avoided. So I am a bit unsure if domtal is a good idea at all.

It is an experiment with an uncertain future.

Sincerely,
Joachim
