Yes, it does - shared libraries, extension .so
The other way is to use separate processes, which protects the programs from one another, and gives you control over scheduling (so the HMI could
run on the same box but in a different process and with lower priority, as a sort of half-way house between integrated HMI and separate HMI).
We should probably move this discussion to the linuxplc list.
