Tusulog complements email and more but we honestly don't think email can replaced completely. It's a simple product that sends and receives messages between people. What it does:

First it turns the basic idea of email upside down that's anybody can send mail to anybody's inbox. With Tusulog messages from people you don't know goes to Public Pipe and also you can disable it altogether. BTW, your friends can send to your inbox directly.

Second with email you apply the filter after getting the message. With Tusulog you apply the filter (pipe) before. PG, taking your example literally: You create a TODO Pipe with public_key THEPUBLICKEYOFPGSTODOPIPE. You give this public_key to people you want. They can send message to that pipe in other words they can put a task into your ToDo list. They can do it using Tusulog UI or Tusulog API.

Congratulations, this looks like a good effort on pg's thought on email being ripe for disruption.

My 2 cents: I think it will be hard to build traction if all tusulog subscribers have to convince friends and associates to register for a tusulog account. Perhaps one way around it would be to allow registered users to accept and send email from/to non-tusulog accounts, with support for handling non-tusulog accounts with pipes. That way you get to enjoy the features of tusulog, without imposing it on others, and avoid the chicken and egg, first fax/telephone conundrums, etc.
