putting the focus on the run command... no problem.

as for running a command on a remote machine...

assuming: machine-A machine-B machine-C

where machine-B runs your main, A and C run 2 clones each.
you set A and C to auto-connect to B
then you add commands to A, B, and C to run wow
(you could have wow1, wow2 for separate directories)

then, on B, after A and C have connected... you type:

A:wow1;A:wow2;C:wow1;C:wow2;wow

and hit 'connect' or enter. (the last wow runs locally on machine B)

this willl run all your wow instances in one shot.
