There are a number of products that will "do the math" and calculate based
upon the size of the HTML page and linked images how long the page would
take to load at a given bandwidth.

This comes from the BBEdit "Document Size" command:

Document Size Profile
==================================================

File:        anvil01:SASi:site_mirror_2001:index.html
URL:        file:///anvil01/SASi/site_mirror_2001/index.html

Text:        6.22 K (20%)
Graphics:    24.87 K (80%)
--------------------------------------------------
Total:        31.09 K


Estimated Download Time:
==================================================

14.4k Modem:        22 seconds
28.8k Modem:        11 seconds
33.6k Modem:         9 seconds
53k Modem:           6 seconds
56k Modem:           6 seconds
128k ISDN Line:      2 seconds
T1 Line:             0 seconds

I have not seen one that does one visually and shows you what is happening.
This would be even more useful for simulating pages with streaming
multimedia content.
