In this case, there certainly is:

ssh remote.host.org "echo $( cat ~/.ssh/id_dsa.pub ) >>
.ssh/authorized_keys"

(This is fine for single-line files like a public key. For multi-line
files, just embed quotes:

ssh remote.host.org "echo '$( cat ~/.ssh/id_dsa.pub )' >>
.ssh/authorized_keys"

Admittedly, this is just as *ugly*...
