KSysGuard seems to have a pretty complete implementation, but it's not in a 
library to link against.  So, we could either harness ksysguard's 
implementation, ktimemon's version, move SK's sensor/meter stuff into some 
centralized location or some other solution that isn't obvious to me.
The code for ksysguard is located here:
kde3.5/kdebase/ksysguard/ksysguardd

It seems all three try to do the same thing, so it only makes sense.  Is there 
a way to make this more of a service than just a central resource for all 
apps?  We could avoid some inefficiencies that way and work towards a plasma 
implementation.
