Pete, yes you can pass a Proc object as the value of the :roles option,
and it will get evaluated when the task is considered for execution. The
proc should return an array of role names.
Capistrano provides a defer() helper to make declaring the procs a bit
easier to read:
task :generic_task, :roles => defer { compute_role_names_here } do
# ...
end
