Hey there, thanks for all these enlightening responses. I have one more related question. When I was trying out kitely, a few minutes after logging in, I could find that things were unusually very slow (am always comparing with am used to that Linden Lab servers). Rezzing a simple cube would take longer than usual. Then after some time, response on kitely improved somewhat. Now am thinking, may be because resource allocation on amazon cloud is somewhat dynamic, could it be that it takes a while for all necessary resources to be allocated ... (I haven't absolutely no clue about how all this happens in the background, this is all speculation from someone who has a lot to learn). Let me know your thoughts. Thanks Ramesh
