Branching and tagging on evs is intimately tied to the database 
structure...  they're only similar in representation in the RCS file but 
that file is only used at a late stage in the process - eventually it'll 
go away altogether (for 3.x).

Adding fast (ie. as in instant) tag to evs is really only a days work, 
since the database structure already has that capablility.  You just 
translate the tag to a date before you pass it to RCS and everyone's happy.

Branching is harder.. a magic branch works because it reserves space for 
the branch in the file when you create it.. it's a relatively trivial 
operation.  Having a completely ficticious branch is one of those things 
that would touch rather more of the old RCS code than I'd like at this 

OTOH it would be interesting to see what you came up with.. getting fast 
tag into the old cvs code is quite an achievement, given its limitations.
