Margin: auto already does work, but requires absolute positioning of
the inner block.  I think the reason that one cannot do it for purely
in flow blocks is that block context is really a vertical inline mode.

If vertical-align: center works for table cells, I would presume, but
haven't tested it, that display: table-cell will do the necessary,
always assuming an adequate CSS implementation in the browser.
