A version of webster I used found over a page of definitions.  The
following looked the most relevant to me:

>From Webster's Revised Unabridged Dictionary (1913) [web1913]:
     2. Hence: (Law)
        (a) The chief actor in a crime, or an abettor who is
            present at it, -- as distinguished from an accessory.
>From WordNet (r) 1.6 [wn]:
       3: an actor who plays a principal role [syn: {star}, {lead}]
       5: the major party to a financial transaction; buys and sells
          for his own account [syn: {dealer}]

Perhaps the MIT originators of the term were amateur thespians taking a
microeconomics course or were considering a career in criminal law.
