In theory this may be true, but ubc-vision gets virtually no news from
uw-beaver. It is apparently used for mail. They also dial up seismo for mail
on a demand basis (actually X.25). 

Whey the ihnp4/alberta link went down, the did get uw-beaver to turn on a
limited number of news groups, comp, and news I think.

The justification for this is simply the cost.

Cost is definitely the problem. Which is precisely the reason for trying to
convince Tymnet to let us access UUNET for $3.00 US / hour. Brings the cost
of a full feed to under $300 per month. We could then see one or two more
full feeds into Canada.
