I do have it up on my site, though it's not being used by members yet (still setting up what it's going to be used for).

If you look at one of my posts (Vilandra) you will see a button in the postbit in the lower left. If you click on it it pulls up a page with the contents of the profile field on it.
If you install the hack as instructed, it would put that button with the pm, profile etc buttons though.
If you want to see the edit profile part of it,
