* you’re spot on, with your statement that your typical smartphone is potentially a little Linux- or BSD-based server.
* part of the reason that smartphone connectivity is unidirectional-initiate (you can connect from your ‘phone to the Internet, but not vice versa) is down to cacheing proxies and the need for many-to-1 NAT; the latter is mostly imposed by IPv4.
* iOS 6 will have IPv6 over wi-fi and LTE (the presenters don’t mention it, but freeze-frame the Apple WWDC keynote video at 107.13); Android ICS has it too (from results of a straight Google search). When the telcos themselves go IPv6, they can keep the cacheing proxies on one side for bandwidth conservation, but it’s “bye-bye NAT, hello bidirectionally-initiated IPv6″.
* I’m hoping the sudden ability for very many people to go self-hosting will see more notice taken of the Mine! project – especially as security-conscious Brits will want to host their own medical records rather than let the NHS keep them (unless Dame Fiona Caldicott injects some sense into current NHS proposals)
* there will naturally be security concerns from smartphone vendors, about setting them up as servers and thus making them more readily attackable. ARM TrustZone is going to help, rather a lot. Power consumption issues could be interesting.

For this to work – says he, persuasively – the phone companies will have to rip out much of the latency-inducing intermediate NAT and other session-based crap, moving instead to pure IPv6 solutions.

Whether this will fully presage running webservers on your phones is unclear – still it would be good to have demand so that technology is nudged that way – but it’s a step in the right direction.

I was just going to glance at the post and listen tomorrow but I got caught up in it and then had to look go look at a few things, Tor, my phone, The coming war on general computation … and now its almost 2am!

Thanks for posting the video!
