I would like to make a proposal here.
I do follow since several years both the DonationCoder environment and the Zero Install project. Call me a shameless connector or whatever bad word you can think of, I don't mind, but I want to say I'm confident that some kind of partnership, in a direction or the other, would really benefit both. Zero Install works on Linux, Windows, Mac OS X, UNIX. Awesome would be if every piece of software, coming from DC developers, even the most little one, could be packaged providing a "Zero Install feed"; dreaming a bit, but not that much, that would also make flowless and easier to accomplish an interoperability between various DC apps (see how ZI manages dependencies), and the software index would include all the DonationCoder apps, so they would be easier to find and explore (and immediately run!
Thinking forward, a donation system in DC style could eventually be integrated in the service and/or the project itself. With Zero Install would be very easy for users e.g. to try DC apps (easy as clicking a "Launch!" button), eventually fall in love with them, and donate for a lifetime unlock.
Really, I see a lot of potential here for both the ecosystems, and I could write a lot about that - but I'll let you use your own imagination while here and now I'll just prefer begging to stop for a moment, and take a serious look to the Zero Install project for the possibilities that your contributions would bring; what I'm asking here is to make your tiny/little/big/huge/whatever apps available as Zero Install feeds (if they work on the supported platforms); of course you can continue using your usual way of packaging and distributing stuff, but I'm asking to make a Zero Install version *too* - it's easy and well explained:http://0install.net/...ector-packagers.html
If you want to explore the possibility, please join the mailing list that is the main place for discussions; also for any trouble in making the feeds, there will be always someone capable and willing to help there:http://0install.net/support.html
