I don't think Beman's proposal relies on any particular svn features. 
Also svn externals break the read-only (http) vs. read-write (https) 
arrangement. Someone who is using read-only access will not be able to 
do updates if put in externals of the https variety, and vice versa. In 
general I think relying on any particular RCS feature is going to get us 
into trouble down the road. But that's just a hunch, so don't put too 
much weight on it.
