a security improvement. Otherwise all you've accomplished is to leave the password-equivalent
in ~/.ssh instead of in ~/.svn. ;)  I mention this only because a lot of the applications
for SSH public keys involve passwordless login.

I feel a little like a broken record, but...

using GSSAPI (or Negotiate for HTTPS) substantially reduces the security
issues by integrating authentication into the rest of a managed
single-sign-on system.  GSSAPI/Negotiate also has the feature of working
in all four remote access protocols for Subversion.  The downside is
difficulty in configuration and poor support in some (or many or perhaps
all) binary distributions of Subversion.  I have to admit, I don't think
very highly of ssh public-key authentication;  I have a hard time
believing very many users or administrators carefully protect, rotate,
and revoke RSA keys in a timely manner, which seems to me to
substantially reduce the security of ssh public-key "infrastructure".
