It's early days, but I've just come across a link to a site which shows you how to use Google Drive to webhost for free.
The link is here: http://www.labnol.or...le-drive/28178/
I've tested it with their sample website file and it appears to work.
I'm sure that there are some downsides to this, but I don't know what they are; with exception to there being a not very nicely named URL.
Apparently it can also be used for podcasts, though I've not tested that. I thought that this might be useful for any of you who want to host websites / podcasts and are on a budget.
I've not tested uploading an individual html/mp3 etc file yet though I am sure that there is a way to do this.
