Web_India - something not yet mentioned explicitly in this thread is the duplicate content filter.

If you are hosting a 2 or more domains on the same IP, G will check whether the domains have:
1. Duplicate content, and
2. User the same directory structure

So this will be another reason you may wish to consider a separate IP. It's the "c" class that I would recommend be different (IP=aaa.bbb.ccc.ddd). There are other threads on ww that talk in-depth about the dupe-content filter. Too late to go trawling to find it for you I'm afraid.

We're about to experiment with the dupe-content filter. So ask me in 6 weeks how it went wrt partically dupe content on same IP for competitive kw.
