Any chance to add a custom port?
UPDATE: just did, see my fork ;)

@ferielboa: just copy this text and save it as ssh-copy-id.py. Then, from the folder where you saved it call python ssh-copy-id.py ceilfors@my-remote-machine. You can also add a custom port for the ssh/scp connection in my fork with the -p flag. It will ask you to login twice, once for the scp and once for the ssh connection.
