Re: [Marnew] [5gangip] [Stackevo-discuss] [gaia] 5G: It's the Network, Stupid

VPNs often have a lot of baggage, notably that an end system can belong
to only one at a time.

Slices have the baggage that a process can belong to only one slice at a
time.

I don't know if we strictly need a new term - virtual networks seems
fine to me (which, IMO, are synonymous with overlays) - but VPNs of all
types and slices have this baggage that is useful to avoid.
