...satellite delay is and will always be "undesirable" (if not unusable)<br>
for the sort of real-time interactive stuff I do, including almost<br>
exclusively CLI environment, VoIP, telepresence (controlling things<br>
remotely)...<br>
------------------------------<wbr>----------------------------<br>
<br>
<br>
I've done these things over geo-sat and they're not as bad as many<br>
try to portray.<br>
<br>
<br>
If you lower your natural human tolerances for interactivity.<br>
<br>
Geostationary satellite well exceeds the 0.1 second latency limit below<br>
which humans perceive things to be responding instantly.<br>

It all depends on how close to the sat radio you<br>
are, how well you've set up your QoS and how skilled folks are about<br>
waiting to talk and not talk over each other.  That last part will<br>
affect the normal uninitiated consumer, I'd imagine.<br>
