Just a brief comment on this.  I don't think that the communication  
portion is the problem, it is keeping the data in a consistent  
state.  If a membership record is being updated because new data  
comes in and a membership clerk is updating that record at the same  
time then you have a potential problem.

That problem isn't impossible to overcome either, but does require  
more work.  At what level do you lock the data?  From a database  
point of view think of this as table level locks versus row level  
locks.  Or for OS people, a big giant lock versus fine grained sub- 
system locks.

Of all the complaints I have about the MLS software, I can at least  
appreciate the trade off on this one.
