After a bit of fingering around Twister, reading parts of code and reasoning on its architecture, hereby my current impression:
1) The libtorrent-raster integration is very interesting. It can be interesting also for the mainline Bitcoind and other clients around.
2) Having a blockchain based messaging system is something I've been contemplating for a while now. There can be so many uses for it!
3) Twister will hardly take off as it is since there is no incentive for running it. There is simply no balance. No gain, just pain for cpus and routers.
I hope to see this or other similar projects being developed in future. Would definitely contribute to them if they go into a direction that I perceive as successful, unfortunately this is not yet the case for Twister, but lets see. It is certainly an inspiring project and the coder is a good one.
My suggestion: give rewards to seed-dns and miners, lets say twistercoins (TWC) and then make Twister messaging accounts cost something in TWC.
