I have been following your spin-off idea since its inception and I have to say it's a really interesting one and I would love to see it implemented, just to see what happens. Are there currently any plans for such an implementation? Unfortunately my coding knowledge is zero but I'm willing to support such an endeavour by donating BTC.
We are working towards a spec for the spin-off protocol at the moment, but it will take some time. Hopefully soon we can come up with a more "decentralized" scheme for donations, as I have received more than a few offers now (which I've so far declined). Thank you for the offer!
This then begs the question of which protocol would be a good candidate for the first try. I suppose it should be one which offers some features which are incompatible with Bitcoins core protocol and thus can't be implemented on the Bitcoin blockchain. This thread has made me painfully aware of how little I know about the alt-coin universe so I don't have any suggestions for likely candidates. Any ideas?
I think the idea would be to launch spin-offs of any potentially interesting new technology. Enhanced privacy Crytonote based coins seem to be en vogue at the moment (although I consider their appeal dubious), so this is an option. If Turing-complete coins start making waves again, a Turing-complete spin-off would also be a logical candidate.
