Out of curiousity, I went through the u.can.on.? files looking for
uunet connectivity:

	jtsv16	uunet(HOURLY/2)
	dptcdc	uunet(HOURLY/2)
	bdofed  uunet(DEMAND)
	attcan	uunet(EVENING)
	mitel	uunet(DEMAND)
	mnetor	uunet(DEMAND+HIGH)
	pantor	uunet(DEMAND)
	paqs1	uunet(DEMAND)
	simware	uunet(DEMAND)
	watmath	uunet(DEDICATED)
	utai	uunet(HOURLY/2)

Assigning numeric costs to some of the symbols, we get:

	DEDICATED 200
	DEMAND	300
	HOURLY	500
	EVENING	1800

This has always confused me, since I thought attcan had graciously
expressed willingness to forward mail to and from uunet, and attcan
has the worst cost in the list!  We've always had watmath declared
dead, so we didn't get caught by their change to DEDICATED.  Considering
how well U of T is connected locally, is it any wonder that U of T ends
up forwarding everything?  Without extra hacking around with a local path 
file, almost every entry in our path file has "utai!uunet" in it.

Incidentally, most of the DEMAND entries were inserted by uunet personnel.

Anyways, I'm going to reinsert

	attcan	uunet(0)

into my path.local file and have done with it.
