Hep

Sergio href="http://blog.portugalmail.pt/K/archive/000166.html#000166">found
this new message server concept that might change the way we
e-communicate. In the author own words:

Hep is a message server. It’s a server in the sense
that it’s a program without a graphical user interface, that runs
in the background, waiting for other programs to connect to it over
the network. I call it a “message server” because it does things
with messages, which as far as Hep is concerned are any little bits
of text or HTML that you want to read, or save, or publish, or pass
on to somebody else, or convert into a different format, or
organize.
