I have several 3- and 4-way switches in my house that I want to enable
with X10.

Sites like X10.com and Leviton suggest using an X10 controller for one
end and then using special X10 companion switches for the other
switches.

I spoke to someone at tech support at one of the X10 vendors and he
confirmed my suspicion that you can use regular 3- or 4-way switches
for everything but the controller at one end.

e.g.,
For 3-way:

[X10 3-way master] <==> [Standard 3-way]


For 4-way:

[X10 3-way master] <===> [Standard 4-way] <===> [Standard 3-way]

The above makes sense electrically since only switch needs to be
controlled remotely. Can anybody confirm that indeed one can use
standard (and cheaper) 3/4 way switches for everything but the master?
