      Ok, I create ~/.ssh/ubuntu_rsa{,.pub} and uploaded
ubuntu_rsa.pub to my launchpad account. I can do the login part of the
show,

raub at desktop:~/docs/Projects/Ubuntu$ bzr whoami "Mauricio Tavares
<raubvogel at gmail.com>"
raub at desktop:~/docs/Projects/Ubuntu$ bzr launchpad-login raubvogel
raub at desktop:~/docs/Projects/Ubuntu$

but the branching part does not seem to work so well:

raub at desktop:~/docs/Projects/Ubuntu$ bzr branch lp:ubuntu-docs
Permission denied (publickey).
ConnectionReset reading response for 'BzrDir.open_2.1', retrying
Permission denied (publickey).
bzr: ERROR: Connection closed: Unexpected end of message. Please check
connectivity and permissions, and report a bug if problems persist.
raub at desktop:~/docs/Projects/Ubuntu$

Since it is barking about a public key, I have to assume it is trying
to use the default one (id_rsa{,.pub}). According to 'bzr help
launchpad', it is using bzr+ssh://, so it would make sense that I can
specify the keys. Maybe it uses ~/.ssh/config?
