Version 1.0 of the widget is now available at href:http://ibiblio.org/mcmahon/widgets/PerlmonksXP.wdgt.zip - it skips the vote stuff for now (but entrprising monks who take a gander at the source code can see that it's ready for it as soon as I decide on a nice way to handle logging in vs. not logging in).

I'll link this from my home page as well.

It uses the XP ticker node (see What XML generators are currently available on PerlMonks?) to get the data. and shows you your current XP and title, the number of points to the next level, and and your up/down change since the widget was launched.

It supports all the standard stuff: multiple instances (so you can watch mulitiple users if you feel like it), internationalization (patches welcome to translate the stirings into other lanfuages). It remembers your ID across restart/logout. It currently restarts the delta tracking on each login; I nay change this to be remembered as well.

I'm planning on adding the voting soon. I'd also be interested in hearing suggestions for other widgets. It was quite a lot of fun; Javascript can be entertaining to write, at least in this quick-feedback environment.

Edit:
Now linked at the top of this thread as well.
