Try looking under /tmp/lam-username_at_hostname on each host. When lambooted
there appears to be a file in this directory called "lam" which appears to
contain the pids of the lam processes running on that machine. The first
appears to be the PID of the lam deamon itself on that machine.
I don't have any documentation that states this, just my observation.
