You also want blast gates so you can close off the hoses going to tools
you're not using to provide extra suction to the ones you are using.  I have
a Jet central dust collector, which I haven't plumbed yet since I'm still
deciding where I want all my woodworking tools to go, now that I have a lift
occupying a big chunk of my garage.  

SAFETY TIP -- If you're using nonmetallic hose/pipe, run a ground wire
through it.  All that fluffy sawdust running along a plastic pipe can build
up quite a bit of static.  If it discharges when it hits the vacuum/dust
collector and makes a nice spark right where you have a bunch of flammable
sawdust with a big fan providing plenty of oxygen, there's a fire hazard.
I've never seen this happen myself, but it sounds plausible enough.
