I had seen this point... and to avoid doubt I am not against being able to 
represent separate processes and show how they might synchronise as in 
Drew/David's type (3) suggestion.  But I am against HAVING to do this is 
there are multiple participants.  I think it should be possible to also 
model a process and map the activities to the participants/roles/ etc. Austin
