Nice images.
Don't expect to find a way of webhosting raw images; that's really not what it's about. Instead, you should consider your raw images as if they're your negatives, and also treat them as your intellectual property.
Use NV, PP, NC or
PS to process the raw images (as if you had a darkroom) with .jpgs as your target for output, and then post smaller, somewhat low-res versions of the jpg to the web.
The reason I suggest low res images is simply for bandwidth limitations; not everybody has access to a high speed connection (thanx Telstra for keeping us in the 1880's) and a 5MP raw file, downloaded over a 56 dial-up connection isn't going to be a pretty sight.
Oh yes, browsers don't recognise the raw format either, so most people won't be able to view images posted as raw anyway.
