Disclosure: Since I'm an ELK dealer my opinions are not entirely
without bias.

You can connect the three structures to the ELK-M1G system using
RS485 rather than Ethernet.  Lighting and other modules can be
installed in the remote structures as needed.  I'll have to check
with ELK to determine compatibility with fiber converters but TTBOMK
it's doable.

True.  Just plan the bandwidth and features you need well before
selecting the Tx/Rx and fiber.  The process is not complicated but it
must be done to assure a successful installation.  Some of the
fiberoptics manufacturers offer online planning guides.  If you need
help feel free to contact us.

Correct.  I would also point out that the ELK M1G controller is a
solid security system as well as a robust home automation system.
It's also one of the few reasonably priced systems available for DIY.
