Not that I know of. As Daniel Berlin said, Subversion 1.4 will probably have
support for checking out repositories with compressed local copies (or no copy
at all -- but I wouldn't suggest this, as you'd start to be slow in "svn diff",
"svn stat", etc).

You may want to look into svk though, which implements a distributed system on
the top of an exising subversion repository. svk working copies do not have a
double-copy at all.

Also I suggest you to look into "svn switch" which might be useful to you to
switch an existing working copy from a branch to another, without redownloading
the whole thing but just the differences.
