You're making a faulty assumption or two here. The current Archipelago use of U.S. mail forces an artificial pace on all conversations. This pace may be appropriate for some conversations; it is not appropriate for all conversations.
The use of direct phone links would remove this restriction, without applying others - assuming a reasonable implementation. At Digital, I have participated in or seen many conversations spanning years - and others spanning days or hours.
