Depends on what one tries to do with it.
You show my how HT is supposed to work well in a "REAL" SMP environment (that being more than 2 CPUs). Call me spoilt for choice, but I find taking dual-cpu system seriously a little challenging at times. Well - comes with the job I guess

.
From what I've seen on it, it's rather an interesting & good approach for dual-proc SMP-ing. But it should be hard to handle when you're getting into serious SMP systems - i.e.: 4-way and up.
I'm not dissing it - it may well evolve that we've got two different busses - one for dual-proc-ing, one for "big" servers.
It certainly will be interesting to follow
