Yes, that is the ultimate goal - and a really important one. Because
what I want is "total mobility".
(Heh, the term sounds a little... fascist. I can assure you it's not.)
By total mobility I mean an infrastructure of freely available
computation servers, open for everyone. Open like the WWW, email and
For that, we need to run code from untrusted sources. If we require
trusted sources all the time, we cannot expand the system the way I
want it to expand.

That is ok as an intermediate measure. But even then: Why would I want
anything I load to endanger my system - no matter where it came from?
Better to just make the system water-tight.
