These type of approaches are how to begin to SWAT proof privacy services analogous to what was Lavabit provided, but some of other issues are: - overlay node discovery, registration (which ethereum may handle) - interop with common protocols DNS/TLS/SMTP/IMAP/IP/"entry|exit" nodes - assure high availability of persistent data - end-to-end encryption - incentivize people to run nodes to provide bandwidth, low latency, storage and computing resources... possibly to rate limit the API and pay/barter nodes with multiple cryptocurrency/ies ( LTC / maaaybe something on top of ethereum in addition to BTC)... more than just for access, but analogous to running a solar array at home and being connected to the grid - ease of building applications and extensions on top of other distributed services (make it dead simple, not over-engineered... ethereum appears to do this)
