I downloaded wikiCalc
today and began to play with it.  It reminds a lot of Radio Userland
…
wikiCalc is an application that installs on your desktop and then uses
a browser for the UI.  It appears to be using AJAX for a lot of
the interaction, and has an interesting publishing architecture.

I really like to see more and more applications like this.  I
believe that they represent an interesting intersection of client and
server … leveraging the power of the desktop, while allowing for
remote access.  I simply point my browser at a “server” – running
on my local machine, or a remote machine – and I am presented with a
flexible UI that contains rich AJAX functionality.

I like it!
