If I understand you right you need to have the sources of both companies
at each location.  Do you need to have write access to the foreign
sources?  In this case I would suggest to access the foreign repository
directly via client/server.  You should avoid to have two independent
copies of one repository with full write access. Sooner or later this will
lead to unresolvable conflicts.

I you only need to have read access to the foreign repository I would
suggest the following:

 -  Export the foreign sources at the foreing repository and import them
    into yours as a vendor branch.

 -  Or Use CvsUp.  This is a general mirroring tool with special support
    for CVS repositories.  It's part of FreeBSD, but also available for Linux.
    Look at http://www.polstra.com/projects/freeware/CVSup/
    or      http://www.freebsd.org/handbook/synching.html
