The other day Byrne released a plugin so that MovableType users could allow Wordpress.com users authenticate to make comments.
That was impressive.
Seeing a Wordpress logo on a MT install you'd have to stop for a moment to wonder if your eyes were deceiving you.
In any case Byrne's plugin works very well and now there's another one which is for AOL / AIM users.
This kind of stuff is what makes Movable Type so cool.
