Though router mac is certainly subject to change.  I could by on my
company network but on a different segment and have a different gateway
mac.  Or when the network guys finally decide to ditch that old
Wellfleet router and put in something from this century....

And what about VPN connectivity?  If I have a VPN open, I'm cool with it
synching files across that - though there still is the bandwidth
congestion issue of course.  I often go months at a time before I'm back
in the office and that's a long time to not have things backed up.  I
think the test/validation/whatever-you-want-to-call-it may need to be
more of a "can I access X location" type of test.  It could be as simple
as a ping or something slightly more substantial as a TCP connection.
You can also get some crude metrics of latency that may be useful to
tune how much/how fast the sync will go.
