Whoops sorry. I was trying Evolution's 'Forward as redirect' and it
wasn't exactly what I thought it would do.  good to know (:

Well, my immediate need is to find the kernel.machine and
kernel.version, and I'm not seeing a method to directly address a given
name space, I've only find examples of searching for a device through
either a string find, or FindDeviceByCapability.  This led me to wonder
if there was a listing of all these 'Find' operators, and I've had no
luck yet.
