There are some extensive retrievable server lists in XML that could be 
quite useable
one currently at refractions and microimages is developing a similar 
one, there is no "simple" standard
for this though so it is a bit of a hack... WCS support would be even nicer
but...

some wms will reproject whatever they have in to what you need 
if you know an extent box for it, but it is definitely not something
you can rely on.

For servers which have gifs I have found that they usually handle them 
better than pngs other wise use pngs for overlays
