Well... I used it, before I went all Diablo-happy. I knew I'd go back at some point, but wanted to try out the new improved mce. The good news: It's not necessary with Diablo, if you're lucky. (I was, the General wasn't, and I think a couple of others may have reported experience one way or the other...) If all you want is softpoweroff, I think that's largely attainable by editing /etc/mce/mce.ini. (I must warn you that there's a warning in mce.ini similar to the one in powerlaunch about making it impossible to shut down... but if you're careful with either program, it's pretty straightforward.)
