Best way to capture SSH output within a Vagrant plugin

[Luis Bosque]

Hi,

I'm writing a vagrant plugin that runs some commands through SSH in the instance and tries to do different things based on the output of those commands.
I'm using "vm.action :ssh_run" to run the ssh comands but I'm having difficulties to capture the output of the SSH command. After taking a look to lib/vagrant/action/builtin/ssh_run.rb and lib/vagrant/util/ssh.rb I can't see clear way to get this output.
What's is the best way to do this?

Thanks
