Keep in mind one thing:
Lots of vty/console activity can jack up the CPU on the router.  If 
the router you want to do this on is heavily loaded, you may really want 
to reconsider doing this.  Disabling the paging with a 'terminal length 0' 
will help clear things out more quickly, but it's still worth considering.

IIRC network traffic TO the router, i.e. your telnet/ssh traffic is not 
processed through an accelerated switching path, so the router has to work 
hard to push those packets, plus servicing the Virtual Exec processes can
also bog the CPU.
