You know...I'm reminded of something we're all familiar with that came
up, oh...lets say 8 years ago. There were some new-fangled devices out
there that were capable of communicating over POTS at somewhere close to
56 kbps. It seems to me there were two flavors of them, K-Flex and X2.
You might have heard of them. Anyway, if your modem had K-Flex firmware
and was trying to connect to something using X2, you couldn't connect
anywhere near 56 kbps. And vice-versa. The two technologies were
incompatible. And yet, once they detected the incompatability, they
were able to renegotiate down to a protocol they had in common, say
v.32. Now eventually we came out with the v.90 standard so that
everyone could play together nicely. Point is, even before there *was*
a 56k standard, all those "incompatible" modems could still communicate,
just not using their new proprietary protocols. So, I guess I'm
wondering....how is what BIND9 does substantially different than the
case I've outlined above?
