Yup.  If you go the JS route then you can do even better by using JS to 
load data into JS objects in the background and manipulate the page 
content directly, no need for even an Iframe.  Ignore the dullards who 
have JS turned off - it's essential for modern web apps, and refusing JS 
conflicts absolutely with proper semantic markup.

http://developer.apple.com/internet/webcontent/xmlhttpreq.html is a good 
starting point.

It's clear that this discussion has moved way away from PG!  Although in 
the context of DB backed web apps I guess in remains a bit on-topic...
