Testimonials at the Hughesnet website indicate that their customers enjoy
having something faster than dial-up. They don't mention satellite's
round-trip delay.
Could anything be worse?
Some of us remember the days when 20 WPM CW over ham radio was considered
fast. Hold a minute while I convert that to a baud rate... ummmm, on
second thought, perhaps someone else has already done the math... Hah!
Here it is, from W8JI:

60 WPM is perhaps about 50 baud. So 20 WPM (faster than I was ever able to
copy) is about 17 baud. Seems terribly slow by today's standards, or even
compared to 110-baud early dial-up.
Even slower were the semaphore and wigwag methods of flag communication:

For REALLY primitive rapid long-distance communication check out RFC 1149.
The data transmission rate? Proper implementation might yield 9102 Mbit/s,
according to this Wikipedia article:
