One thing to keep in mind is that there are very good reasons to try to
keep probes as simple as possible. Even if that means installing 4
probes in one location.

Extra complexity translates into extra testing effort and more bugs.
What is gained by using the hardware more efficiently can be lost easily
in more engineering effort.

At this moment, making a probe multi-homed would be a significant
engineering effort because just about all code implicitly assumes that
every probe has exactly one interface.

(I assume that from a hardware point of view, VLAN tagging would allow a
probe to be connect to different ethernets)
