Spideroak allows online viewing via web interface. Anytime you use the web interface, however, you give up the zero knowledge portion as they need your password to decrypt the files. Also there is a shared folder feature that allows you to create a separate share password to give out to other people for a folder. Presumably use of this feature also gives up on the zero-knowledge at least for that folder.
