You'll face a lot of those problems on residential ISP connections too. The bigger issue with mobile devices is that they're roaming between towers, so there are frequent changes to the network topology. But p2p networks usually require a long-ish bootstrapping step that might not even finish by the time the physical network shifts underneath it. (Tor bootstrapping takes on the order of ~30 seconds, for example.) As the linked paper notes, this is disruptive not only to the local client, but also to the rest of the network that needs to re-learn (and re-propagate) the location of mobile peers.
