opening a port without root permission

Hi,
Is there any way one can open a port, in my specific case - the ARP port, so that I could do an Arping without a root access ?

Or is there any way the root could give permission to a user to open a port ?

Or does anyone know a way by which I can extract the MAC address of a remote machine in a different subnet, where I do not have to be a super-user?

Any pointers would be greatly appreciated.
Thanks.
