I'd guess Google Drive.
You could get a website that points to wherever the download actually is.
That's one of the suggestions on G+ too. I didn't think that they would show up in Google proper and get indexed, but someone said they had for him, so maybe I will go with that. (Even if it doesn't work, I can always redownload and upload somewhere else, presumably.)
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Of course, for "every Monday", the last one should have been dated July 22-28. *cough*
