FCS RTMP, What is it, really?

FCS RTMP, What is it, really?

I am a big fan of FCS.  And, actually, officially, yesterday, I can are
now say we are using it successfully with some of our clients, instead
of Windows or Real for live streaming media.  But, unfortunately, at the
same time, I have quite a few clients that are having problems getting
FCS content through their firewalls.  

I have read all the articles on the web about RTMP (there aren't that
many, none that I can find speak to the actual protocol).  And, I have
asked and received some good information from the FCS community via
e-mail discussion threads.  Yet, I still do not really understand this
topic well enough.  I have clients interested in using it FCS, but first
I need to speak to their IT Infrastructure departments about "allowing"
RTMP traffic through their firewalls.

The questions below are NOT about the setting on my server, or how to
set up RMTP, RMPT, HTTPT, or how to check/use different ports, etc.
These questions are about RTMP.

*  *  *  *  *

What really is RTMP?  Is it proprietary to MM?  How does it differ from
HTTP and/or RTSP and/or MMS and/or any of the other protocols used
today?

How are firewalls stopping it, when I have httpt running? (packet
sniffing?)

What setting need to be changed on a firewall to allow (or restrict)
RTMP? (some sort of packet sniffing setting?)

If the setting where changed, are there security implications (worms,
viruses, etc)?

Does any other company/application, besides MM/FCS use RTMP?  Is so,
who/what?  (I am hoping one of the IM services.)

*  *  *  *  *

Can someone from MM answer these questions?  Can anyone answer these
questions?  Where can I go, who can I talk to, to learn more?

Thanks, Troy
