I assumed it probably uses something digital fountain stuff covers
given that they did mention it somewhere in the paper.  Regardless
that warning is standard practice with these algorithms.

I was disappointed that the paper didn't really cover the
computational costs.  cpu vendors would love this stuff.  gotta have a
multicore machine with memory bandwidth to sit there continuosly
computing new codes over your entire dataset. ;)
