This kind of thing is best done on the client as much as possible. This
Internet Groupware, discusses this kind of thing in pages 396 ff,
"Polymorphic HTML Widgets". He produces code at the server using perl and
cgi methods, but you could use xslt for it. Send the data and some special
client might still have to come back to the server, but not necessarily.
For another example, you could look at this url:
make a selection from one of two pick lists, the code selects and displays
the data subset in the other frame without ever talking to the server again.
Granted, 200K is a little extreme, especially for low-bandwidth modem
connections. But once it's loaded, you're all set.
This particular page is done using Cold Fusion and a relational database,
but you could use XSLT with the data in xml format to do the same thing.
