There is no ongoing work in that area at the moment, and nothing planned. Furthermore, we are in the process of bringing major changes to the layout engine in order to be able to handle pages of different widths. So any work on the current code is likely to become obsolete soon. Like Sean said this is a complicated problem. CSS2 gives some indications, but it remains to see how applicable they are when you take everything into account (some columns having a set width, using percentages to specify widths, fixed row heights, row and column spans, page breaks, etc.). I suspect that a constraint satisfaction problem might show up [1], or maybe something that can be solved with the simplex algorithm [2]. At any rate, a theoretical study of the problem, without looking at any code, would already be of great help. Things like studying the XSL-FO Recommendation, trying to think of every situation that might occur, looking at how web browsers behave, and gathering thoughts in a wiki page [3]. If you want to give it a go, switch to the fop-dev mailing list [4] to ask questions and share thoughts.
