Hmm, I think it is all about interfaces. If the interface is
simple and general purpose, it might be trivial to adapt device
drivers. For instance, I believe that a simple interface will
enable us to reuse existing drivers for Windows Vista or Linux,
what might be necessary is an interface stub implementation for
Windows, for Linux etc. to reuse those drivers.

Nah, I think if you stuck to the Unix/Linux/Plan9 userland, than
the whole idea of writing a new OS gets irrelevant. I believe
the challenge is to find a completely new and different OS
design, esp. from a userland perspective. Otherwise all design
decisions will be similiar to what Unix did decades ago.

Nothing, I understand Pikes paper as request for something new,
that is neither Unix nor Plan 9/Inferno (though the latter ones
come with really great general purpose concepts). I won't think
about a new OS to replace anything existing, I think about an OS
which is so different (hence new) as a demo only, that it might
show up as a promise for something in the future. It would be
enough if such an demo OS would make a specific but rather
limited thing easy to use, like a digital camera, a mobile
phone, or something else. I believe for a small community and
project, there are not enough resources to attempt replacing an
existing full-featured Windows or Unix OS.
