The whole point of VPLS is to simulate a multipoint Ethernet segment, possibly across a WAN and several MPLS PE routers. If you only have a small network it is usually far simpler to just set up a suitable collection of switches with VLAN trunks between them. So the question is - *why* would you want FreeBSD to support VPLS? And what exactly do you mean by implementing VPLS on FreeBSD? If you want a multipoint bridge across several interfaces, this can be done. If you want something with MPLS support (labels etc) it's a completely different ball game.
