Overriding CVS/Root with pserver

[Ed]

Suppose I have a working directory on host devbox, and the CVS/Root admin 
file contains ":pserver:address@hidden:/cvsroot".  Is there a way for 
address@hidden to override this to login and/or commit changes to this 
working directory as, say, address@hidden, *without* modifying the 
.../CVS/Root setting?  It seems any CVSROOT env setting is ignored during 
login.  I know this is not considered kosher, but is there a way?

TIA.
