The above links are good not necessarily because they are up-to-date or comprehensive but because they show unwitting evidence of how people outside a particular country see that country's universities.

Just a rough guess, but it looks as if the OU is about as expensive (for overseas students) as a US university would be (for residential students).

Brits abroad

http://news.bbc.co.uk/2/shared/spl/hi/in_depth/brits_abroad/html/ - an old survey, but confirms that most British expats still live in 'Western' European countries, so (as per the post just now) the expansion of the OU in Eastern Europe will happen as English language proficiency increases (or Brits get really good at learning Eastern European languages...)

This is a very interesting publication - out of date - but contains a wealth of information on the higher education sector in Europe. It's a long download (250 pages). Section C on fees is interesting - very big differences across the Continent.

As long ago as 1999 http://www.timeshighereducation.co.uk/story.asp?storyCode=148460&sectioncode=26 the Commission decided to collect statistical information but note that even back then they were very careful not to say anything in favour of the idea of regulating or harmonising fees.
