I have some experience with what you are asking. While not from the =
DSNG side, I have experience with satellite based IP using iDirect =
Infinity shared satellite hubs. The 5000- and 7000-series Infinity =
remotes will support SCPC between two remotes if you wish, but it's all =
IP based.
Getting into the emergency response arena would require an IP based =
network. I have done this with the City of Chicago for several =
communications trucks that my former employer built and maintains for =
them. They send and receive live video, VoIP, and enterprise network =
data across the satellite. They have a dedicated space segment that =
they buy annually so they don't run into the issue of not having =
satellite connectivity available when they really need it. Trying to =
sell this together to your employer possibly means a merging of your two =
disparate capabilities. Can you move your MPEG streams over IP?

Intelsat operates several iDirect hubs available for public use which =
are tied to the Internet. They should be able to help you with your =
occasional use needs. If you need a contact, I can try to dig one up =
for you.
