Why does it have to be over UDP at all? Couldn't we just role a new layer 4 protocol entirely?

Didn't Apple use something called Multipath TCP for mobile connections? Is that vaguely related to mobile IP?

Because of the myriad of firewalls and routers that don't understand IP protocols that isn't TCP or UDP. IPsec tunnels were commonly encapsulated in UDP packets for this very reason because its safer to assume that at least one device alobg the way won't understand protocol 50.

Multipath tcp isn't really a new protocol as much as it is an extension to tcp and wouldn't offer the benefits that UDP would as it is still constrained by (and benefiting from) the design goals of tcp.
