Until now I didn't implement any of the features you mentioned. But most
certainly it can be done using the current implementations of DHTML,
Javascript and DOM in IE or perhaps Mozilla.

I believe that the server based solutions are the gap fillers, because 100%
client side processors are

 a) much faster because they
  a1) don't need a network roundtrip for every action
  a2) only read data but no html
  a3) may cache static xml data
  a4) don't reparse the whole document all the time

 b) more secure because they a1) ... therefore the guys on
    the server side (and nobody else on the web) can track
    your actions

 c) still working (against local data) when you're offline 

 d) easier to implement because you don't have to use
    HTTP GETs and POSTs

 e) easier to deploy because you don't need a web server
    and/or servlet container
