Raw

Anyone found/tried a good way of getting data out of Gmail en masse? The UI/tagging/search of it works pretty well for me, but because I subscribe to lots of lists I've been at the space limit for ages and deleting chunks of the archives is getting a pain. I tried a popular search engine, didn't see any obvious answer.

Ideally I'd like to get the stuff out in a form that was easily navigable/searchable (SQL? Atom? RDF?)

 

Not that I'd cast aspersions on their scalability, or arithmetic...
