Re: Running Commands on multiple systems

[Nathan Andelin <nandelin@xxxxxxxxx>]

My first inclination would be to write and deploy a command-processing web
service on each system and pair it with a command entry client. Enable
users to broadcast requests to all systems, or selected systems. As an
alternative to web services, I'd look into setting up remote DB server
entries and using an SQL interface for running commands on selected remote
hosts.

Just some thoughts to stir discussion.
