RE: Added costings to pilot plan and resources

Geez, 

These weekends conversations are HOTT !! :)

Seriously now are we saying their will be no protection on the client
side (UPS) ?? Ace is spot on with regards to sessions being executed on
the 
Server (HD and Mem) the only concern is if the clients don't have UPS 
In the event of a power failure and dies, although the Data resides on
the "server" there are concerns of abnormal termination and defunct
forks 
Which will eventually affect system performance, and should be taken
into consideration..

Excellent. I was hoping that the this would be the case. This will 
massively reduce the cost of our installations (around 40%!). I will be 
conducting some experiments when I return to T&T (actually I don't leave

till Monday but that's moot). I'll provide a definitive answer on this
then.
