Very nice use case @farmerd, I can see you've put quite some time and effort into this. Would one of your farmshare UIA tokens hold a maturation period, i.e. to comply with the 'buy in spring, shop at harvest' of current system?
Will read more up on this worker, have thought however for a long time BitShares it would be great to have a really innovative, user-friendly and highly intuitive with built-in steps and community help, a dedicated UIA Token Factory application ..
