distributed repositories

[Thomas Olausson]

Is it possible and/or has anyone set up CVS with 
two different repositories, allowing distributed development, 
and then having an admin or a script merging them together periodically.

I'd like the two different groups to be able to develop on their own,
but not having to touch the other group's repository, at least not
individually.

I'd like to mimic the funcionality in Rational ClearCase.

Regards,
 T
