Apart from Glastonbury, where everyone seems to take car to the venue, most people with tents are travelling light and compact, so I imagine the wind charger will be a little large. Not to mention how much noise will it make whizzing away over your head? (Okay, again not that likely to notice in Glastonbury, but when camped out in quiet countryside I'm sure you would).
My own personal solution (I do actually own one for bike rallies/fishing etc) is a FreeLoader http://www.solartechnology.co.uk/products/Solar_chargers/freeloader.asp.
Which is only slightly bigger than my Nokia N70 when packed down, and that's including it's own Li-Ion battery which it charges.
