Hi Raman, > thanks, and sorry for bothering you with inappropriate questions It's not that the questions are inappropriate in-as-much as the collective expertise on this forum isn't concentrated in the domains you are interested in. As I read it, the intent of Brian's response was not to chastise you, but to help you find the answers you seek from knowledge-experts in the domains you are inquiring about. Sincerely, --Eljay
