So with the way my house is laid out it and the difficulty in running network cables it would really make sense to put the server rack in the spider-filled basement, and a network switch on each floor. But while thinking about cost effective ways to achieve that (including use of the long distance stacking feature of the classic Brocade ICX switches or just running some of those Chinese 2.5G softrouter boxes) I keep coming back to this idea of instead setting up a BGP routed WAN or similar.

By running redundant cables I gain resilience against the chaos I live in (multiple kids and pets plus pretty frequently reorganizing furniture to get all of us to fit comfortably in our 1200 square foot starter house) plus by using a routing protocol like BGP it should do some amount of load balancing to allow more bandwidth between clients (I find peer to peer network technologies super neat so i love experimenting with them) but the thought also comes to use those Microtik router cards for even more bandwidth

Honestly it's a lot of ideas I've been bouncing around while my family spends all of my hobby money on things like mini vacations that we can all enjoy
