The original purpose of the heartbeat was simply to provide a
mechanism through which the hub was able to co-ordinate connections.
It's also useful, of course, in enabling discovery of active
applications on the network and it also provides a potential
mechanism for failover between apps.

I think notification of generic errors of this type should probably
use a standard class as a matter of policy (e.g. xap-user-error, xap-
technical-error) and intercepted and displayed in A.N.other GUI --
just because there's so many potential combinations; it would be
difficult to cram meaningful error descriptions (end user
description, error code, application state etc) into a poor heartbeat.
