I'm a sole developer in pyjamas coding in the lounge room trying to come up with an idea that will make an income when I'm not doing my day job to pay the bills, in case you're asking if I am a rich company trying to get free development services. I'm happy to reciprocate technical services if what I know is of value. I write open source code too so I'm contributing although not to the libgit2 project.
Same as many other developers here on HN I suspect. Coding in the hope of building something people want to use.
So, you're looking for somebody else to do at least some of the technical work for a passive income project, without some sort of profit-sharing arrangement or transparency about that fact (until I brought this up)?
Truly rich companies are more likely just to pay for talented developers or services than small folks--see also aquihires.
Anyways, enough of the business/philosophy stuff...what are you looking to gain by using PG as a backing store?
