    Do you mean?

    # mv ping ping.real
    # chmod -s ping.real
    # mkcapwrap +net_raw ping
    # chmod +s ping
    # showcapwrap ping
    invokes /bin/ping.real
    grants net_raw
    #

    The wrapper needs to setuid/gid to the uid/gid that invokes it.

    uid root with no caps (or few caps) is still very powerful (replace
    binaries owned by root, read /etc/shadow, etc).

    Currently all capabilities are cleared when non-root app does a execp.
    This would need to be addressed.
