Well, my understandin is that backgrounds is obsolete/no longer
developed and the right thing to use is textbackgrounds. You can
define textbackgrounds and they work fairly well. The documentation is
a bit lacking, but details manual as the basics. Defining new
backgrounds can be tricky, as the backgrounds work well in
multi-column documents, break across pages and follow grids! You can
not ask for more.

textbackgrounds are a bit more robust. They work better with the
option that Hans suggested in

Last time that I seriously used textbackgrounds (in typesetting
homework solutions) I had a few problems near the page ends.
Occasionally a large equation would not split across the page boundary
and would hang outside the page background. A \page[bigpreference]
would usually set it right. The math stuff was in the intial stages
then, and I do not know if it was math alignment at that time (early
Jan/Feb 2006) or the textbackgrounds. I did not really get time to
clean up the project and test the whole thing. My cleaned up solution
of using textbackgrounds is in my practex article
http://tug.org/pracjourn/2006-4/mahajan/
Overall textbackgrounds worked fairly well.
I have been thinking of making a library of different text
backgrounds, so that one could say
\definetextbackground[whatever][background=background:oval] and get an
oval background. Basically just a collection of commonly used
backgrounds (oval, random squeezed, random puked, frame, random frame,
all of the above with a shadow, etc.). What I had in mind was not
something with lot of configuration options, since that will be hard
for my knowledge of metapost context interaction, but something simple
which shows how to define new backgrounds, so that one can modify the
examples according to their needs. But it is a bit low on my todo list
right now :-(
