cvs question

[Hem Bapat]

I have a question regarding how CVS can be configured to work with multiple
development sites. Let's say there are three development sites in the US,
Russia and India. US site has the source code repository and developers
here have access to all of the source code(C/C++/java). Russians can only
access C++ source code and cannot access C or java source code. Whereas
Indians can only access java source code(checkin checkout etc) and cannot
access C++ or C source code. Is it possible to implement a model like this
using CVS?

Your reply is appreciated.

Thanks,
