this seems like a natural outflow of the discussion that's been going on with regards to how to fund various features, in particular, the thread about implementing stealth transactions and a private investor willing to take the risk.
one of the ideas proposed, or at least how i understood it, was creating a worker proposal that states that a UIA and the funds the sales of this UIA would be used to pay the developer for a particular feature. see :
https://bitsharestalk.org/index.php/topic,20207.0.html .
what stan proposes is essentially the a sophisticated version of this idea, marketed with a pretty bow (not to say that we shouldn't consider marketing when presenting ideas), but presented as his own.
essentially, features that we want developed can be funded by fee backed assets, and over time provide income by charging shareholders who use such features. those who invest and own said fba's profit.
great. i approve (minus certain parts, which i hope are clear).
the reference to the origins of this idea (or at least when i first encountered it) actually included in this post.
