You can set $Conf{RsyncSshArgs} to a command that simply executes its
arguments (like ssh does). However, rsync adds the host name to whatever
you specify in $Conf{RsyncSshArgs}, so unfortunately this doesn't work
since the first argument is the host name, and env will give an error:
$Conf{RsyncSshArgs} = ['-e', '/usr/bin/env']; # <- this doesn't work
A very bad hack would be to use something like this:
$Conf{RsyncSshArgs} = ['-e', '/usr/bin/sudo -p'];
(sudo has to be passwordless from the BackupPC user.) The -p (prompt)
option expects an argument to set the password prompt (which is not used).
So it consumes the host name argument appended by rsync, then runs the rest
of the command like ssh does. Bingo - the client rsync gets run locally,
with elevated privileges from sudo, without ssh.
An alternative would be to write a short shell/python/perl script instead
that does it more cleanly - shifts the first argument off argv, and execs
the rest.

V4 allows you to have an array for $Conf{ClientNameAlias} to support this
behavior (checking several different host names in order, and picking the
first one for which ping succeeds).
