What would that achieve? USB devices can only talk 'upwards' towards a host, not sideways to another device on the same network tier. You can bodge the standard to make it fit but that's non-standard, or 'cheating'

I don't see a power supply on the board, nor do I see a power connector.
"massive retard™", "full of shit™", "tiny bitch™", "retarted™", "a bit of a one trick pony™", "petty™", "simple minded idealistic twat™", "miserable humourless fucker™"
Or it could be powered through the HDMI connector's power pins.

You're right: rooting through the spec, it's the source that supplies the +5V power.
Fuck knows how Breadbin's use case of plugging a TV into the HDMI port and a keyboard into the other end (which he talks about at the start of his BBC interview) is going to work, then...

It won't. This is intended to address the issue of kids without access to a proper computer, which roughly is reckoned to be ~5-10%. http://www.bbc.co.uk/news/education-12075057

Am I missing something here?
I took that to suggest that with a generic OS on it kids are likely to treat it like they do any other desktop and download porn and go on facebook and generally do an awful lot of things with it that aren't programming.
Whereas in the 8-bit days you had to issue at least one BASIC command before you could download porn or go on facebook or do anything else that wasn't programming.

Yeah that looks like the plan, this does not achieve that though, it just address' the issue of computers not being available to all. This is just a cheap affordable computer suitable for kids - "One piece of the jigsaw".
Also on that site : "How would you use an ultra-low-cost computer? Do you have open-source educational software we can use? Contact us at info@raspberrypi.org."
To be clear the main thrust of this is to teach kids programming rather than spreadsheets and word-processing a s a lot of school courses do these days.
Also a majority of the languages recommended in this thread already exist for it.
The missing piece is course work rather than hardware or software.
