Debug and Virtualization

Here is an incomplete thought I've been having over the past few days. When debugging programs which run on both server and client [like browser code and server code], it can be a pain to figure out what's going on where. However, somehow, I think that virtualization can be used to help abstract a layer or two so that debug can take place more independent of OS [of either or both the client and server OSes].

I noticed that when a program displays stuff on browsers, you have at least 3 layers: the code printing, the text handler and pixel handler. This is true with graphical browsers as well as text [lynx] browsers. When you have layers, then opportunities exist for virtualization. How can it be possible is something I'll have to chew on.
