Home network. This could be wired or wireless.

Think of the backend as a fileserver. If you can have centralized
file storage given your current home setup then it's not a far
stretch to have a network of MythTV boxes.

My house is wired. This skews my perspective a bit.

All of my MythTV drives are shared on the network so that anyone
in the house can see them. I have NFS shares for the Linux boxes
and SMB shares for the Windows boxes.

The frontends mount those shares as if they were local disks and
uses them as such. The frontends access the mysql and mythtv itself
as another network service.
