1. Is there a real need for another book such as the The Book Of Linux Music & Sound ?

3. Would anyone be interested in co-authoring the book ? I've considered offering some chapters to certain people on these lists, but the issue of reimbursement gets sticky WRT royalties and other compensation. I made very little money from the first book, but money wasn't the true reward anyway, so perhaps there's a way to turn it into a community-based work.
