Correct. Keys are nice, but should not be needed.

Yes... (I assume that you've checked your username, etc):
* on Linux, especially with distros like gentoo, you may need to add an
"askpass" utility to your environment to ensure that you get prompted
for a password
* could be an incompatibility with the Twisted library you have
installed (on Linux only, we ship our own one with OSX builds)
* OSX, I will try to test again, what version are you using?
(unfortunately, I don't have every version available for testing..)
