Actually... I personally have no idea. I presume you want to show data from some remote machine, right? Well all scripting inside LCDstudio is C#, so I would guess, if that http server does XML exports, you can import that data into LCDstudio, even through a custom variable, actually, and then do whatever you want with it.
I'm sorry but I'm not particularly willing to start installing weird software just to test out the case. If anyone else is willing... please, be my guest.
Live long and prosper...
