No you haven't missed anything, and I have experience with both feeds. My
Internet feed will get bogged down at least once a day in Chicago, I use
tracert, to locate the slow downs. However satellite is more dependable it is
slower sometimes as much as 30 seconds, usually 10 to 20 seconds on indices, and
index options.
I'm running DTN RT side by side with Siginal-On-Line. The one advantage to
signial that I have found is that the Signal Data Manager lets me run more than
one program on the same feed at a time, as it uses TCP/IP. The biggest draw back
is the 500 symbol limit. On my DTN system I am archiving 36,000 symbols. Support
from DTN is excellent and they have fixed a serious problem they had with the
Index Options, being slow and missing Bid Ask quotes, they still get a little
behind at the open but I never put on a trade at the open, anyway.

I'm curious what the attraction of an internet feed is.
Obviously, it's convenient for non-real-time data, end-of-day,
or make-up data. And the ability to use a browser interface
gives the promise of some platform independence - presumably
your browser could run under Linux, or a Mac, and no-one would
be the wiser. :)
But for a real-time situation, the question of reliability becomes
paramount, and that means a connection to the net that is always
there, especially during RTH. And from what I read, typical packet
loss on internet routers runs above ten percent, not to mention the
all-too-common configuration screwups that render portions of the net
unreachable for minutes or hours. Believe me, as a list manager, I
see plenty of this every day. This sounds potentially worse than the
cable feed I abandoned because the cable company was so fond of
playing with their equipment during market hours. My satellite feed
has had exactly one outage in five years - when the Galaxy 4 bird
lost it.
Then there's the cost; even if the data is free, what do people pay
for that high-quality ISP? Last I checked (admittedly a while ago)
people thought Eskimo's $100/month was a really good deal for 24/7
connectivity. Yes, this is less than BMI's base fee, but when you add
the cost of the extra telephone line (about $60 out here in the
sticks, or maybe down to $30 if that new wide-area rate the local
telco is considering goes through), it's not much less than BMI.
DTN is even cheaper than BMI, and offers satellite service.
I assume the RT exchange fees are the same for net feeds?
So, other than the points mentioned in the first paragraph,
what's the attraction? Am I overlooking something obvious?
