I know that Melvin Smith (aka Mr JoltCola) was planning on a full scale rewrite of imcc. His plan involved SSA. I don't know what came of that; I think that he ran out of tuits... But you might ask him where he is. I cc'ed him on this email... Matt -- "Computer Science is merely the post-Turing Decline of Formal Systems Theory." -???
