Good article on the use of LPR/LPD as a general-purpose distributed queueing mechanism for non-printing applications.
I maintained PLP (the predecessor of LPRng , which the author uses) for a while, and this kind of thing was one of the main featuresets I wanted to enable.
I know someone in (if I recall correctly) BASF was using it to generate movies, from frame-grabs individually LPR’d by a network of machines. As a result we had to add sub-second accuracy to the queueing; not sure if that made it into LPRng though ;)
