well, dm isn't necessary for that.  you could always make the individual
games setuid, for that, but dm's primary purpose is to regulate access to
the games.

easier?  probably not much, as many of them still need a security sweep
anyway. it's a loss of functionality, though, which is objectionable.

there is at least one security issue existing in the current code.  i
invite y'all to come up with an alternative to running dm(8) setuid,
but retain its function.
