Hi Jamie
Somemany have written an article here:

It is incredible that no one has thought of that before.

Quote: "... Using this technique, Zeilinger and co-workers found they could obtain differences in quantum number as high as 600 (in other words l = +300 on one photon and l = ?300 on the other). Lapkiewicz points out that there is, in theory, no upper limit to a photon's l value, which suggests that a photon ? a quantum object ? could acquire as much OAM as a macroscopic object, leading to what he calls a "tension between the quantum and classical worlds" ..."

Quote: "... Indeed, he says that they aim to produce devices that can emit different OAM values at the same time. This, he claims, could enhance telecommunication bandwidth, by increasing the number of channels available, and boost the power of quantum computers ? devices, still under development, that promise much faster data crunching by processing multiple quantum states simultaneously. "Currently, quantum computers rely on electron spin or photon spin, which only have two states, whereas OAM has many states," he explains ..."
25 June 2012, BBC News: 'Twisted light' carries 2.5 terabits of data per second:

Quote: "... Recent work suggests that the trick could vastly boost the data-carrying capacity in wi-fi and optical fibres ... The idea is not to create light waves wiggling in different directions but rather with different amounts of twist, like screws with different numbers of threads ..."
University of Southern California (2013, June 27). Breakthrough in Internet bandwidth: New fiber optic technology could ease Internet congestion, video streaming. ScienceDaily: Quote: "... the technology centers on donut-shaped laser light beams called optical vortices, in which the light twists like a tornado as it moves along the beam path, rather than in a straight line ... Unlike in conventional fibers, OAM modes in these specially designed fibers can carry data streams across an optical fiber while remaining separate at the receiving end ..."
