Sorry, this is getting a bit off-target, but it's relevent to the case for 
appliance based XML processing. 

I think this is a fairly well understood hardware problem if you are comparing 
special purpose hardware to general purpose hardware. Intel etc just have way 
more resources for making improvements in the long run. 

What you can do is use a tight mix of software and hardware to get the best 
out of both without blocking future hardware improvements or for that matter 
software improvements. It's not a hardware or software thing, but a 
hardware/software mix traded at different levels for performance/flexibility. 
Working out what the mix should be is the hard part.
