i think most are fine with it being pure aros bounty, me included, one can include os3/68 port if necessary so os4 and mos users can try it out at last before deciding if they need it too.
edit: just in case this is interesting for anyone, jens prepares an edition of a new fast zorro lan card, so mayme anybody has an idea if this bears any opportunity, like an example of a driver for instance- (cooperation might popularize aros among amiga users a little)
