[thelist] Google Question

[Scott wolpow]

I am creating two sites that will be branded and marketed differently.
They will share a common database and structure.
They also will resolve to the same IP address, which basically constructs 
the pages dynamically.
The problem is I do not want Google to mark them as Spam as they may appear 
to have the same content.
They are both legitimately different sites.
Any ideas?
