I should point out that my previous advice was for Capistrano 2.0;
Cap 1.4.1 does not support the :host option to run().
You can discover all of the host names that are associated with a
particular task by doing this (also, cap2 only):
servers = find_servers_for_task(current_task)
That will give you an array of Capistrano::ServerDefinition objects,
each of which can be queried for the "host" attribute:
hosts = servers.map { |s| s.host }
Hope that helps,
Jamis
