Hi All,

   I feel like a Toffoli disciple. I cannot recreate the argument right 
but he argues that an increase in entropy is compatible with reversible 
and irreversible
processes, but a decrease in entropy is only compatible with reversible 

   The argument is interesting and the book where it appears (he was 
talking at
the "Data Ecologies 05" event last year) is due out "some time soon"...
