No, it's an inherent problem whenever a packet-switched, multi-user, shared channel inherently built around queued transmission tries to emulate real-time protocols, the earliest of which is "a directly-connected wire." This sort of substitution can work, but it requires very stable, low-noise links (that is, with little to no burst noise) and the cooperation of devices and network equipment.
