I don’t know about you, but I was really bored about inserting my password again and again when pulling hg based projects.
Since I’m using Gnome, I decided to check if it was possible to integrate Mercurial with the Gnome Keyring.
Guess what:
http://bitbucket.org/ebo/hggnome-keyring/changeset/4f8cbce98fe6/
Just download the extension and install it, by adding the following line under [extensions] in your .hgrc file:
hggnome-keyring = [PATH_TO_EXTENSION]/hggnome-keyring.py
When pulling from a hg repo, the system will prompt you for the password just for the first time 
Take a look at http://pypi.python.org/pypi/keyring
If this was merged as extension, there would be general cross-platform solution
