Not what you want I'm sure but if you're using a Linux box, or a Linux box as 
a home firewall, you could always setup some quick and dirty QoS to rate 
limit the outbound Ethernet so that it's effective speed is that of a 56K 
modem. (Cringing just thinking about it.)

I've never setup QoS on Linux so I'm not sure how difficult it really is. If 
you do go this route then the major advantage would be you could visual watch 
the pages load and tweak the HTML / Images based on the results.
