Umm... most standard website hosts allow any type of file to be uploaded and linked to, but obviously if you want a free solution things start to get a little harder because, as you say, most handle your uploads by presenting the downloader with a download page.

How much space are you looking for to use for this? If it is 1GB or less than you are welcome to use some space on the classicamiga server. If you wanted to do that I can set you up with a subdomain and ftp access, then you can upload whatever you like and use it to do whatever you wish, even create a website if you wanted. I could give you submeg.classicamiga.com. Let me know if you would like that and I can set it up for you later today.
