That did make me smile.  Mayor of London is (Red) Ken Livingstone who is always making controversial statements but I cannot imagine him saying that about education.
Although I am sure many people have reacted to his speeches as you did in your dream.  My favourite fact about him is that he is a herpetologist (keeps newts).

Miles has given you a direct and useful answer.  I would like to direct you to a discussion that I have found very useful in dealing with log data http://moodle.org/mod/forum/discuss.php?d=19488#94476
I am just thinking that if I was one of your teachers, I am not sure I would welcome a log file that might be huge (even bigger in PDF?) by email but this thread would show them how to downoad as many log records as they wish (to Excel say).
BTW a little tip to retain the date sequence of these records in Excel when sorting and manipulating them is to a sequence number column (since the date is in text format and not sortable).

That sounds really interesting.  Where would the proposed tasks come from?

I agree Ray.  People will share (not in the strict technical non-copy sense described by John Ilsner) when they feel comfortable and trust each other, and that can and does happen in an OS community (though not universally ).  My point about context is an additional issue though.  Sharing learning objects in a repository or local library can get over some of the technical problems, and community trust can ease the problems Ray describes but we do have different contexts for using learning objects and 'learning designs'.  How do we evaluate an LO or LD and find an appropriate way of using it?  We can use structured searches of repositories and study the meta-data, or we can hear about how it worked in practice from someone whose opinion we value.  I think we can learn a lot from the broad range of uses of social software like Blogs and online communities, especially ones like flickr.com and delicious.  Someone uploads a funny image to flickr.com or video to google videos, and then it spreads like a virus though personal links via email lists, blogs,etc.
I wonder if elgg.net will present some good opportunities for an educational version of this.

So, do you think it is individuals who are being precious about what they own or institutions claiming ownership? or a bit of both?
I think that it is easy to denigrate people who refuse to share but probably more productive to understand why they do and don't share - how sharing 'works'. (Please don't interpret this as being against Open source and Open content).
BTW, my post didn't say the problem was across institutions rather than within institutions.
