Windower Plugin For Item Tracking?

Are there any windower plugins for tracking items/pops/key items and so on? I run a large shell (50+) and keeping track of who has what is hard, at best. We've used spreadsheets and forum posts and whatever else, but it's invariably out of date.

My ideal solution would be some kind of windower plugin that would peek in my inventory and key-item lists, and then send a list of what I've got up to a website. The website could then organize who has what, and so on.

Is there a plugin that comes close? I haven't looked into writing my own yet but surely this is an issue other shells face.
