That's greatest schematic I've ever seen! One glance and you easily
see how the multi-switch works.

Exactly what I've got. The 'X' switch is a piece of cake to swap.
I'll have to examine the SPDT to see how they're marked, maybe it's obvious there too.

Of course they are; how else would anybody wire them? The common is
different from the two travelers; the location of which terminal is
common is _not_ necessarily the same physically on various switches.

But, see the comments earlier--it still doesn't matter how you arrange
the travelers or orient the switches themselves in the boxes _unless_
you're also willing to only use them under very restrictive operating
conditions--otherwise they'll migrate to alternate positions w/ time as
the various ones are operated to turn lights/appliances/whatever on/off
individually. Soon unless you again do the exercise of placing them all
individually back to the one known state you still don't have the
desired result in general. That result is just not possible(+) w/o
those kinds of restrictions (which pretty much defeats the whole point
of having multiple locations to begin with).

(+) Again, w/ conventional house wiring using 3- and 4-way switches. It
could be done as others have noted w/ additional relay logic or such.
