That is a very large download.
I'll second the ideas of torrent, filtering by category, version, best of, etc.. and also not in a monolithic archive, though if you've already gone through the work of packing them together I don't see why you'd need to undo that.

Sure, go ahead and make them available as a download.
It's also important that you link to armageddongames.net, zeldaclassic.net, and purezc.net since that is where newer zc versions can be downloaded, updates of the quests can be found, and where to go for help on a quest or to maybe contact the author.
