I think the short answer is no. Arguably all countries in the world are short of good teachers for all subjects.
However, while I recognise (and encourage) the Foundation aim to improve the situation in UK schools, a lot of the ZX80/BBC Micro nostalgia on this forum shows a whole bunch of folks who educated themselves when given the opportunity. I figure the RasPi will give many inquiring minds a chance to play despite the fact they don't have suitable teachers in their normal classroom. But www will be their classroom and like all schools there will be some great teachers and some horrific ones.
