I see..
Well, I wasn't trying to download whole of it in, say, one day. A site like that should have enough bandwidth so that it could be downloaded in couple of weeks/ one month.
If what you say is the sole reason, how about putting it into a big .rar and on emule network? That won't eat a lot of your bandwidth. (maybe just a bit in beginning)
I need offline access to it, and don't mind the updates&fixes 'cause it has already a lot of games
Why don't you put what you have now on DVD and sell it for the cost of media?
How large is it anyway?
If all of this is "undesirable" or whatever, how about archiving just textual data, without pictures, that can't be too large?
