This is, kind of, possible. Can I do it? Personally, no. I don't have the tools - but here is a way you could do this. Sort of
Parsing program: ACT - http://advancedcombattracker.com/
ACT has the ability to parse multiple games via plugins, and a plugin can theoretically be created for any game if it has logs.
Here is the post on plugin creation: http://www.eq2flames.com/plugin-disc...her-games.html
It wouldn't be like, say, a World of Warcraft DPS meter, where its natively updated in a game window. But ACT does have an overlay if you play windowed, and also has an option to save to HTML files. Plus, it exports the data to the clipboard so its paste-able ingame.
You could have a setup where you're running something like XAMPP on your PC, behind the game, and have ACT saving it to somewhere in the HTDOC's folder.
You could then use the ingame browser to bring up the ingame browser redirected to that localhost address.
