Zwave switches 3way and 4way?

I dont see any 3way or 4way Zwave switches for sale.  What am I missing?  The room I most want to control has several of each.
 
Thanks

Don't know how Zwave switches handle it but Lutron switches use the traveler as just a digital signalling wire, not as a traditional carrier of line voltage.  I've got one circuit with four locations, one has the dimmer (load) and the others are just the remote dimmers.  

Z-Wave switches handle it the same way.  There are lots of options, GE, Leviton, Cooper, HomeSeer, etc. all have companion switches to be used for 3 and 4 way applications.

Here's a good table with a number of options and reference to the remote/companion switches: http://www.homeseer.com/compare-z-wave-on---off-wall-switches.html
 
Here's the Leviton one for a switch: https://www.amazon.com/Leviton-VP0SR-10Z-Digital-Coordinating-applications/dp/B001HT4M70/ .  They have a similar one for dimmers.
