Well, looks like I don't have free bandwidth :-) The recent release of Hibernating Rhino #8 has made it clear, since it resulted in a bill.
Now I am looking for a solution for that. We are talking about files on the ~100 - 200 MB range, downloaded tens of thousands of times, over long period of time.
I thought about setting up a torrent server, but I can't find any viable torrent server for Windows, and I don't want to run the torrents from my machine. (I have a server available, if needed)
The other option is hosting it someplace that doesn't mind the bandwidth. Any suggestions?
