Zwave co-existence and device replacement questions

[johnnyt]

Can two zwave networks co-exist? If it matters, in my case one is my "production" 500-series ISY994iZW, and the other will be (not done yet) my "development/testing" Zooz 700-series USB dongle on my Polisy with an unconfigured IoP.

As I test away, and in particular test things like the ZooZ ZEN17, which needs an exclusion/inclusion performed after some parameter changes, I wonder:

1)  How is one supposed to manage changing a parameter that needs an exclusion/inclusion, like with a ZEN17? No big deal when I first get it, I can start over, but what if I have to change something after a bunch of stuff is configured?

2) how to replace a defective device?

Is there a way to assign the same device number that was excluded to a new one on inclusion? If no, which is what I think, is that going to change some day? is/will there ever be a way to add a new zwave device and click "replace device with..." (like there is with Insteon) before excluding the device or after the device failed?

I have 2 Zwave networks at home, one with ISY and one with ISY on Polisy. There is no issue having 2 Zwave net works.
