The problem is that raw files are normally developed in some way. This developing info is normally held in a database (like lightroom) or in a sidecar file. So you wouldnt nromally want to print the raw file as is. Ive looked around for online photo storage for raw files with sidecars, where the files are viewable online, and have found nothing. The only other option is to store the files on an online backup service, like sugarsync, mozy, carbonite, amazon etc.
