Neat :)

Right now hydra.gnu.org is in this weird situation where people who use
it have to trust it, modulo "guix challenge" of course.  But really all
we have to trust is the mapping from the derivation (like the "foo"
package) to a hash of the build results; the actual build result could
be transferred from anywhere with no trust issues at all, provided that
we verify the hash.  (Do I understand the situation correctly?)  Anyway
it would be very interesting to be able to distribute the build products
using more scalable channels without having to trust more people.
