Well, I indeed stumbled upon this in a academical context (my master 
thesis), but the application I'm developping actually has practical uses 
(Media Asset Manament system, the uploaded files are raw and unencoded 
video-files)

Perhaps I should try to split the files in pieces of less than 2GB, but 
I think I will have to do this outside the browser (as no 
client-side-technologies are able to access files, if I'm correct?)

And no, I didn't tried a 64-bit browser, cause I don't have any...
But I don't think that would be a practical solution anyway :)
