LPC_Fan,
Dont be caustic - its not required and we are all watching this story unfold
with objectivity. Your emotional sarcasm denies you the credit of being
considered wise.
When Phillips  come back from Holidays they may - or they may not, put our
minds to rest.
At least Jaya will be able to discuss their argument at a level higher than
I have time to prepare for - and I love him for it.

The best outcome for me - and I assume for others, is that Jaya says "OK -
ur CRP strategy works " and then I have no need to worry.
But its GFREAT to test the Phillips design..and they should apprectiate it
as well.
Send the man champagne - a credit to my alma mater
