What kind of doors does it open if we assume a persistent, reliable connection and treat 'disk' as more of a caching layer for the vast amounts of data available on the web.
Just as RAM and hard disk have their own performance considerations, I think this new layer could be characterized via the following set of properties:
- Read-only (or maybe read-write on servers you own or limited write capability on sites offering some kind of web services)
- Volatile (really depends on which sites are hosting the data, but in general probably don't want to assume that whats there today will also be there tomorrow)
- Virtually unlimited storage (and ever-expanding),
- Extremely cheap (free, subscription, or pay-per-byte)
- Very slow (but getting faster)
- And finally: intermittent failure
