This setup is a pain for both the user and the administrator. Additional
steps must be performed by each before work can begin.
(And ssh keys are really no better than a password, you are just
 forcing the user to have different piece of secret information.)

Why not use something like kerberos? Windows will transparently
checkout a ticket. No password needed and no additional setup needed
by either the user or the administrator for new users. Granted, this
only works well in a corporate environment, but it is a very big win
when dealing with less technical users...

The beauty of Subversion is that it lets YOU choose the
appropriate authentication method for your environment.
