A tool like this should be reasonably easy to implement using the SVN APIs (or language bindings). You could fetch the log, check which pathes are added/removed/changed, and fetch the added/changed files via "cat" functionality. However, if your files are big and the network is slow, this might be actually much slower than update, because it transfers the whole files instead of just the differences.
