Have you looked over the HT consortium site? It is truly a lovely spec

Guys, this is misunderstanding history. AMD was not positioning HT as
an expansion bus until we came along. Even after that, it was clear
that PCI Express was going to have most of the market, so it's only the
folks with high-end needs who might even consider directly attaching to HT.
No FUD required, no lack of energy, nothing weird, and this isn't a
*bad* result. It just is. The highest volume solution tends to be
the one that's good enough, and PCI Express is good enough for most
uses.
I don't disagree, although even their earliest pictures had more than
just CPU and memory hanging off the network. As in CPU, memory, a PCI
bus and several direct attached devices were on most of the
transparencies that I recall of AMD's roadmap presentation 2-3 years
ago. I think that even then, they had a gleam in their eye, although
they also may have been realistic about their chances...
You might want to edit the widipedia page on this, as it states
"Hypertransport has largely fallen out of favor with the networking
community, in favor of SPI 4.2 and PCI-Express" which definitely implies
that at one time it was IN favor...:-)
