That's just it. To get a good loop of images, the 15 minute imagery is
simply beyond comparison to a loop with 60 minute increments. But for
those who can handle the 1KM feed, why NOT make it available to those who
want it? I mean, with the increasing technology (heck, even at NIU now
we're on a T3!), the bandwidth and costs will go up/down respectively and
I suspect every UNIDATA member will eventually be on the VBNS or multiple
T3's to handle it in the next few years. In the last 3 years, we've gone
from a 9600 baud feed from a bird for McIDAS sat pix, to a feed as fast as
the Internet can go.

Just my $.02. Gee, can you tell I want those 1 KM pix? :-)
