Can Perforce or CVS run in a mixed mode envoirment.
i.e. VOBS or storage area on one platform (unix) and VIEWS available to
another platform (Windows NT/2000) either locally or over network.
Clearcase may have a heavy System Admin load but support from Rational
is execellent and documentation is very good and all in the one place.
Guess you get what you pay for!!
