Loading Interior Objects from Zip Files

I'm loading interior objects through script calls using:

%obj = new InteriorInstance()
	{
		position = %x@" "@%y@" "@%z;
		rotation = "0 0 1 "@%rotation;
		interiorFile = %fileName;
	};

I want to start enclosing my interior object files in .zip files - the zip file would contain the .dif as well as the textures and etc. that are required by the dif. Is there a way that I can access this data from within the zip file at runtime (through scripts)? That is, is there someway I can make the same function call I made above where the fileName will point to a dif file that is enclosed within a zip file?

Thanks!
