Funny, I was thinking about this exact thing today. Quantum teleportation essentially is teleportation as long as you avoid the philosophical issues (e.g., is a reconstructed person the same person anymore?) and just stick to the scientific questions. The Bekenstein Bound is a very high upper bound on the maximum information contained within a given volume. Black holes are maximal entropy objects, and since entropy is just the log of the number of states of a system (states = information), roughly speaking, that's how the bound is calculated. But everyday life isn't nearly as high in entropy as a black hole, so it's likely that the amount of information representing a person is significantly less than what the bound suggests. However, I have doubts about whether you can actually use that bound on something that isn't a blackhole. A wavefunction (which is, theoretically, all the information necessary to completely describe a system) is a multi-particle function (more specifically, a function of a configuration space). For example, you can talk about the wavefunction of an electron, but that's just an approximation. To completely describe the electron's behavior, you need the wavefunction as a function of the electron and its surrounding particles. The further away the surrounding particles are, the less of an influence they will have on the behavior of the electron, but the influence is still there. So really, you'd need a wavefunction of everything extant to exactly describe the electron... Anyway, the question of whether there is a "universal wavefunction" seems to be debated among physicists, and I'm not one anyway, so who knows... Getting back on topic, I'll just assume that the wavefunction of all particles constituting a person is enough information to completely specify them and proceed with that as a given. That being the case, there is something called the "no-cloning theorem" that forbids the duplication of a quantum state. So the good news is that there's no way for teleportation to screw up and create two of you! Quantum states can only be moved, which is what quantum teleportation is. The problem is that this teleportation also requires a classical channel (aka an optical fiber) to complete the transfer of state. So, you still can't teleport anything faster than the speed of light. Which isn't much of a problem on earth, but you still can't get to Pluto instantly. This assumes of course that someone far in the future has figured out a way to quickly ascertain the quantum state of macroscopic objects, which is unlikely to ever happen.
