bfd-like mechanism for LANPHY connections between providers

[Tassos Chatzithomaoglou]

Are there any transit providers out there that accept using the BFD (or 
any other similar) mechanism for eBGP peerings?
If no, how do you solve the issue with the physical interface state when 
LANPHY connections are used?
Anyone messing with the BGP timers? If yes, what about multiple LAN 
connections with a single BGP peering?
