Unfortunately, not at this moment. The way tun/tap is implemented is
that there's 1 tun device, which is multiplexed to support all
subscribing slices. What you're suggesting will involve creating
multiple tun/tap devices.

This is not unreasonable, but will require some hacking with vsys and
the network configuration tools. If you *really* need this
functionality, then please write a vsys script that safely
instantiates and configures a new tun device, and makes it visible
only to your slice (you'll need to hack the util-vserver package to
achieve this). Once this is ready, we should be able to test it and
deploy it.
