Are Windows Administrative Tools possible on U3 flash drive???

Any number of administrative tools for windows servers would be a big boost to all fo us admin's out there. I hate having to install tools on workstations to perform one simple task - or having to run back to my office or the server room to add a user or reset a password in Active Directory. I realize that the Windows MMC's are tightly integrated into windows but is it possible that these admin tools could be made to run on a U3 Smartdrive?

I found a great little solution for remote desktop client and VNC viewer called "damn small linux" which runs just fine off of my U3 key, but having the tools themselves would be even better. Can you shed any insight on this topic?

Thanks and keep up the great work....
