The key component is the plain (really, 2-levels) structure of mutually interconnectable nodes (and their users) which can exchange files.

No: FTS-0001 may state (in the next edition) that dialup nodes are required to support EMSI, and IP nodes are required to support binkp.

Yes. And now it's time to actualize it.
