I have one of these:

on my 15" TiBook. It folds under the laptop elevating it from whatever 
surface would normally be trapping heat. Also handy for its intended 
purpose, as well as starting conversations with people who haven't seen 
its like. It tends to keep the fan from going full bore when under 
moderate load (four or five ssh sessions, iTunes, browser, mail.app, 
etc.), but under heavy load (compiling anything) the fan still goes to 
max. My Ti is a 550, so YMMV.

There is a handle available for the 17"; I have no idea if it works 
similarly:
