Accidentally posted before ready.
Any word on when Netsukuku might be ready? A guesstimate, even?
Maybe I shoulda used the actual http://lab.dyne.org/Netsukuku rather than the wiki. Also, I possibly should have paid more attention to the last news update. On the other hand, there has been some recent activity on their http://lists.dyne.org/lurker/list/netsukuku.en.html, and there's a little recentish additions and resolutions on the http://bugs.dyne.org/my_view_page.php. So it
looks like it's either dead or on life support, though I could be missing something. However, if lots of people show an interest and advertise it a bit, people with relevant skills might get interested too and pick it up

.
Problem: many ISPs use https://en.wikipedia.org/wiki/Sandvine to slow P2P traffic to a crawl, if they don't disconnect you from the Internet first.
There are ways to deal with that. A good VPN service, for example, will make the data you're transferring pretty much immune to that kind of thing. Of course, there are other angles of attack that ISP's could go with, but I don't think businesses would take kindly to their networks being breached (since one of the biggest uses for Virtual Private Networks is employees accessing corporate networks while off-site), and I imagine it'd start getting too costly to be worthwhile.
