A suggestion to consider. -- Suppose that the snapshots are always generated by using a CVS checkout that never references the head directly. In other words, in a manner that others can reproduce at a later time. (For example, a checkout by date, using yesterday's date) Now this "key" can be placed in a file within the tree where interested parties can retrieve it. Since the key is only a line or two at most, and only affects one file, it will not impose the burden on CTM and CVSup that a full scale CVS Tag would create. Richard Wackerbarth
