too bad they don't say what the bandwidth is at max distance - anyone know?

I am installing a 1500' link in a few weeks. If you are interested, just
ping me
for the results at the end of April.

I considered that but the Linux boxes also give me the flexibility to
traffic-shape with AstShape as well as use IAX trunking; to use the remote
Linux box as a SIP demarcation point with IAX back hauled to the primary
LAN. Also, in the event of subnet congestion, I can subnet the remote LAN
and use the Linux box as a router, it's pretty trivial to do. Haven't
got to
that point yet since just running SIP over it seems fine right now, but I
can't preclude it in the future, my users are very bandwidth-hungry and
their needs grow and grow daily, using Linux gives me finer-grained control
over how these services are delivered. 

Besides, hey, it's Linux, how cool is that?

Before I get toasted through and through - you would still need the VDSL
extenders of course, but the Linux boxes seem like overkill...

Because of rights-of-way issues that happened after the copper was laid, it
was impossible to lay new fiber. The objective was to create a close to
100mbit as possible, redundant, and prioritizable (sp?) link using the
existing copper. 

The link just functions as a plain jane bridge right now but sticking Linux
in the mix allows for future QoS and routing enhancements when the remote
location grows. This is a large consideration because the company I work for
is experiencing 100% yearly growth with no end in sight. 

Thanks for the comments. It was a cool learning experience for me; I'm
actually suprised and impressed that it works so well. Ping times are
precisely the same as the local switch! When the users moved over, they just
plugged in. 

Yay Linux
