"... current system status (current CPU, RAM, free disk space, etc.)" And "*nix and Windows platforms" can be a difficult combination to achieve.

The operating systems are fundamentally different in the way they manage these resources. Indeed, they differ in core concepts like defining what counts as system and what counts as application time.

"Free disk space"? What counts as "disk space?" All partitions of all devices? What about foreign partitions in a multi-boot environment?

I don't think there's a clear enough consensus between Windows and *nix that makes this possible. Indeed, there may not even be any consensus between the various operating systems called Windows. Is there a single Windows API that works for both XP and Vista?
