Yes, this works for the framed environment but not for the floating parts,
which was what I meant. I just wasn't able to express myself very well...
I did some hacks a while ago to make framed work with color (and colors in
pdftex in particular) and continuation texts. In order to make that work I
introduced different frame types depending on whether there were page
breaks or not. However it doesn't solve the real problem of floating
objects that might occur in the text, which is why I searched for a
different solution. Using eso-pic to draw the frame or shading behind the
text seems to work very well, but the hardest part is getting the correct
positioning information out from LaTeX. I used \pdfsavepos and friends to
do this together with ntheorem and empheq, where the endmark algorithm was
abused to write its position to a file. Blasted authors - think they can
have all their wishes come true... But since they pay then...
I imagine this sort of thing would be much easier with the LaTeX3 output
routine in a combination with the galley2 package. I'm reading up on the
latter these days - rather intricate stuff but it's that kind of approach
we need to get things right (and colors and all that hyperref stuff to
