I guess? Well, suffice to say, one does need special equipment to communicate over a VDSL line, it's not just applying a different protocol over a standard NIC.

I guess? Well, suffice to say, one does need special equipment to communicate over a VDSL line, it's not just applying a different protocol over a standard NIC. The only PCI-E VDSL2 card I've seen is the Draytek VigorNIC 132. (Which, BTW, should really also have a low-profile backplate. :/ ) I can't deny I'd be curious to play around with it on an x86 OpenWRT system, but at about 200€, it's a bit pricy... My current setup has a latency of 8ms, of which I'd speculate that at most 2ms are due to the router+modem? Could an x86 "monster" router+modem bring that down to 0ms?
