Installation is documented at
https://github.com/mkdesu/cables/wiki/deployment. The init script is
for Gentoo, yes — it needs to be adapted for each specific
distribution (this is mentioned in the documentation).

No, non-direct routing is not supported by the protocol — Alice and
Bob will need to be online simultaneously at some point, when the
queued message will be delivered.

Yes, this can be easily achieved by configuring Nginx, FCGI spawner,
and the cables daemon so that separate FCGI services / cables daemon
are used for each user (presumably executed under the relevant user
credentials). Having a single service / cables daemon access multiple
users' private keys and mailboxes is possible to implement, but
problematic from the security perspective.
