Terabit Internet Possible Using Twisted Light?

Just great, after reading this article, Chubby Checker singing "The Twist" in stuck in my head. Thanks to AliceCooper for the link.

The wireless and fibre-optic links that make up the internet use electromagnetic waves to carry data as a series of pulses at a specific frequency. It is possible to increase the amount of data transmitted at a given frequency by twisting light beams in different ways. Each beam has a different angular momentum and acts as an independent channel in a larger, composite, beam.
