I have a script called svn-switch-patch that undoes the changes in the 
local tree and applies a patch on top of it.  It is not perfect (you 
cannot have three-way conflict resolution), but it is good enough for 
most occasions and you actually end up having *less* stuff on disk.  And 
it can be used offline exactly because of the working copy.
