Without the tunnel services PIC, the only component which can do tunneling
is the routing engine. Without a tunnel pic you can still configure
tunneling, and it will work if you want to tunnel out the fxp0, but since
Juniper turned off the PFE->re forwarding (to stop people from trying to
route with the fxp0 I guess) you can't do it if it involves sending the
packet over the normal hardware. Personally I think it is a shame that you
can't do 64Kbps of v6-in-v4 tunneling without having to buy a tunnel pic 
because some twits called for support on their fxp0 routing configuration,
but when has useful functionality and easing the adoption of a new 
protocol ever stopped a router vendor before. :)
