[boost] Feature Request - Combine or provide Interop between Boost Filesystem & Iostreams Library, Virtual File System

Just a thought if boost file-system could be user-configurable with boost iostreams library we could have a nice, clean API for virtual file-systems (VFS) not just for the OS file-system. For example the other day an associate of mine wanted to be able to read/write/etc to a zip file like a OS file-system, he couldn't use boost iostream's zip filter since it doesn't apparently provide that kind of behaviour/abstraction but boost file-system does provide that kind of abstraction/behaviour the only problem is it's pretty much tied to working with OS file-systems only as far as i'm aware.
