I mean, there are only 4 people behind my router, ... but I've also worked in businesses where there could easily be only 4 people behind the router, and they just use shitty commodity hardware for that. So my "Home Network" could be considered more "professional" than many "Professional enterprises" =p

I have personal issue with this rationale, because I do things frequently in a home network environment that I might also be inclined to do in a small corporate network, ie: setting up a BSD Router w/ DHCP / NAT / DNS / IPv6 / Mail , etc, and it really is my "learning" platform so I know how to do that before I try do it in a paid capacity. So for me, "Home setting" is very, very vague.
