I can, we use this for several purposes, one is to
extend or modify the VFS namespace by mounting or
unmounting filesystems _into_ the guest

we (Linux-VServer) extended the set/enter_namespace
command to take a flag mask similar to unshare
(only 64bit wide :) to allow for 'selecting' the
proper spaces
note: the nsproxy a context is referring to can also
be changed this way, and a priviledged process can
enter each guest space separately ...
