[IBM; obs.] IBM's SNA (Systems Network Architecture), an incredibly
{losing} and {bletcherous} communications protocol once widely
favored at commercial shops that didn't know any better (like other
proprietary networking protocols, it became obsolete and effectively
disappeared after the Internet explosion c.1994). The official IBM
definition is "that which binds blue boxes together." See {fear and
loathing}. It may not be irrelevant that Blue Glue is the trade name
of a 3M product that is commonly used to hold down the carpet squares
to the removable panel floors common in {dinosaur pen}s. A
correspondent at U. Minn. reports that the CS department there has
about 80 bottles of the stuff hanging about, so they often refer to
any messy work to be done as using the blue glue.
