Load new app.nw into same instance

[maur...@tabuleiro.com]

Hi. I could not find a simple way to load a different app.nw bundle/package into an open app. Is this possible? Scenario is to package several sites/html5 objects as different .nw packages, and have a way to load a different one from the same node-webkit executable. I guess I am looking for something like a FILE->OPEN menu that could open a .nw package, which I understand is not available. Any tips about how to implement it, probably by modifying the shell and calling some Package:: methods?
One other option I considered (that would not require modifications to the cc code) would be to implement at the content level perhaps, as an html5 app, and using the node libraries to locate the .nw files at the filesystem. Any quick route to pass a filesystem object from node to be opened as a package in the main shell?
