also, for truezip we would have to really reengineer and dive into their codebase to layer the VFS on top of it. Currently, MOST of it is married to java.io.File implementations and not URL based. Their nested jar support extracts jars into temporary files. None of it that I saw allows you to provide a InputStream or URL as the implementation is based fully based on RandomAccessFiles.
