COBRAMUSH  [codebase]
A PennMUSH fork with its own division and power model. Small deployment, still
answering.

  Nothing was offered in any handshake we have read from them.

CobraMUSH forked from PennMUSH and added a division model — a hierarchy of
administrative authority with delegable powers, in place of the flat
wizard/royalty distinction its parent uses. Games that want to hand out slices
of staff authority without handing out everything are its constituency.

Softcode written for PennMUSH mostly runs, and the differences concentrate in
exactly the area the fork was about.

WHAT IT LOOKS LIKE FROM OUTSIDE

No MSSP, a working pre-login WHO, and no telnet options negotiated at all on the
game we measured. That last part is not a criticism: a server that negotiates
nothing is a server that cannot get negotiation wrong, and plain text over a
plain socket is the thing every client in this hobby handles.
