Does anybody have any recent performance and capability statistics (eg. forwarding rates with full BGP tables and N ethernet interfaces) or any pointer to what the current state of art in software routers is?

I'd like to be wrong, but there's no way that any PC/Commodity routing 
system is going to work (in any environment other than Ethernet).  For 
the small ISP starting out (you know, the ones selling T1's/xDSL), there 
are no Channelized T3/OC3 cards available for a PeeCee, which means you 
still need to buy something from Cisco or Juniper.  And the major 
carriers are already using Cisco/Juniper, because even at the price they 
charge they aren't unreasonable because they support their product.  I 
don't care how many packets per second, or simultaneous route flows you 
can do if I can't plug anything besides Ethernet into it.  If you can 
show me the hardware, great I'll take a look at it, otherwise these 
simply don't matter all that much.
