Apparently, it's now possible to load a package from a remote  
location on the web.

I put a simple init.m file that defines a function HexToDecimal at  
this url:

         http://www.math.armstrong.edu/faculty/hollis/init.m

Entering this quietly loads it:

         Import["http://www.math.armstrong.edu/faculty/hollis/init.m";]

For verification, enter this:

	?HexToDecimal

Stunning.
