Anyone know of an OS/Software inventory tool that supports Linux and Windows that is agentless?
No, but ocsinventory-ng (http://www.ocsinventory-ng.org/) has an agent rpm for centos in the epel repository and a remote deployment tool that makes putting it on windows and other linux versions fairly painless.
The server is yum-able from http://blog.famillecollet.com/post/2009/04/21/ocsinventory-1.02-1-en (epel must also be enabled).
If you want more than just computers in your inventory, it also integrates with http://glpi-project.org/?lang=en
