What it ultimately comes down to is just the fact that I have to make sure I'm spending my time wisely. Every moment that I spend in conversations like this is a moment that I can't be in the code, making improvements, fixing things, or adding new features. Unfortunately there has to be a line, and I feel like we've crossed it already.
I should have stated above that there's more than SAMBA involved here, including VMs and network routing within the same machine, which can be funky to begin with. So regardless, nothing here is a common scenario. I use SAMBA network paths myself for storing ROMs, but it's known that images and videos should really be local due to performance requirements.
