At my company, we continually are looking for new providers for shared storage. Right now, we're on Dropbox, but I'm evaluating just throwing them all into Google Docs since they give us free storage and we can copy/paste direct URLs for files into IMs and e-mails.
Can you compare Nasuni's offerings to Dropbox and GDocs? The "choose your cloud" is nice, I suppose, but that's way too complicated for me as a business person who can barely write SQL.
