Hey Steve,

when you

term% plumb whatever

you operate wthin the namespace of the rc window, when you mid-click+plumb, or 
right click somewhere you operate in the namespace of the system, which you can 
examine for example by:

plumb 'Local ns>/tmp/main.ns' # at least if you have no strange /tmp binds (as 
with ramfs)

Anyway plumb 'Local …' is your friend when building the system namespace that 
is used for the mouse clicks.

But the plan9 plumber even much more flexible than that, as you can start 
concurrent plumber in one system or mount remote plumbers to exchange data with 
remote machines. So the concepts just feels like Copy&Paste Operations on the 
first glimpse, but can be extended to get you completely confused, when you 
don't know what you're doing.

So always know your namespace, or at least the customized part of it, is a good 
first hint, I think.
