Cal, I'll do my damndest to try and find you some cheap/free hosting for files. Mine is only £15 a year but that's a gig of transfers a month and only 50mb of space on the server. £1.50 per gig of transfers extra isn't too bad at least.
OR. How about we go to a bittorrent solution. It means we'd all be downloading the latest videos off each other. Takes a bit of community working and good will for people to leave the files seeding, but it would certainly save on bandwidth.
