I want to have the formula numbers of cases environment flushed on the right like for regular formulas (not the default numberdistance=2.5\emwidth). How can I do that?

As far as I know, this is not possible right now. You can play around with numberdistance setting of the cases environment, but it moves the equations to the left (as the whole structure is centered on the line). If you really need this, one option is to use metapost page backgrounds with a mathalign environment; place anchors before the x and y glyphs, and then use metapost to draw a left bracket. See the metafun manual for examples of using metapost anchors. Aditya
