Heh - just when you think you've gotten most of the useful references for your job, you find something new. There is an extremely useful paper that was published last year by a group at Sun Microsystems that seems to have followed many of the same threads I've been looking at, and has not only interesting content but a VERY useful reference section :-). There's even a mention of the problem with economic conversions in the reference review :-).
