I found myself writing that same for loop and using cluster type tools to manage multiple windows as well.

The for loop takes a long time to do anything significant on a large number of machines since it runs serially (and is a pain if one or more of the hosts happens to be down).

The multiple windows solution only scales as far as your screen size (assuming you are checking results as you type).

Then I ran across shmux (http://web.taranis.org/shmux/) which works like the for loop solution, but tackles hosts in parallel while tracking errors and keeping logs.

The author lists quite a few more alternatives at the bottom of his web page as well.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
