Part of the reason is it is going to vary a LOT. Licensing costs are going to
vary according to how many licenses you buy, what MOSS/SQL/Windows editions you
use, what purchasing program you go through, etc and hardware will vary
depending on vendor. Could you be more specific about what MOSS features you
would be looking for, how many users, what type of users (employees vs.
clients/internet uses), what sort or performance/scalability/availability, etc.
