I'm sure delta compression is used in many specialized applications, but I do not know of browsers that support it in the general case.

http://www.wyman.us/main/2004/09/using_rfc3229_w.html is the only general-purpose, broadly deployed use of delta that I've heard of.  The Windows RSS platform supports this feature, as do a number of other RSS clients.

i'm writing a book and would like to include a section on
http delta compression. i found two products that do delta,
does anybody know any others that are available now?

do these both work by using javascript to send delta?
anybody tested these?

it appears that netscaler is here:

citrix netscaler

and fineground is now part of cisco's application velocity software:
