If you know a programmer willing and able to build one to my spec, please have them contact me. I've been looking for one for a long time.
I do have one lead but haven't had time to look into it fully.
Keep in mind my stuff is relatively bug free to begin with and very resistant to breakage. During the 2 yrs Nightfall has been out, I've only had to issue 15 releases (compared to SOE's 29). I'm guessing that's also well below the number of updates from most major sets.
Between patches uploaded by other users and my official releases, SOE changes are generally resolved within 24hrs. EOF was a bit of an annomally since several key windows were radically changed. In comparison, when SOE reskinned the default UI, my set was unaffected.
There are also disadvantages to auto-updaters, most notably they usually step all over any customizations you make to the base set.
At any rate, I know many of my users want this option so I'll be happy to work with a programmer to get it done if one volunteers
