I am TortoiseHg core developer. I have also contributed a few changes to core mercurial and I maintain the ProjrcExtension, which was originally developed by MartinGeisler @ aragost Trifork, and sponsored by http://www.lantiq.com/.
A while ago I gave talk about mercurial and TortoiseHg to the Malaga DotNet Users Group. You can check it out at Mercurial and TortoiseHg basics.
