Re: Optional text base design discussion?

Sure a caching proxy would be a different way to implement this behavior. I
was thinking more along the lines of this being a new wc model directly
though. However I don't think one excludes the other, and that if such a
cache backend was created you could probably use it directly for the new wc
code as well as to implement a caching svn proxy.
