Closing this as invalid for now, since this doesn't actually mention what the problem is you'd like to see solved. bzr-svn already uses the windows and keychain providers if they are available, can use gnome-keyring through bzr-gtk and I would expect qbzr to provide something similar for kwallet.
Feel free to reopen if you disagree, but please with more details :-)
