This is all SD video (no HD at all) ...

If the backend and frontend are not on a LAN.
If they were connected via broadband.
So Low Quality recording and viewing is acceptable.

Then - What kind of bandwidth requirements are we talking about?

First off, MythTV was never designed for this.  You have
to expose your MySQL server to the outside, which is a
bad idea.  Worse, you have to expose your backend to
the outside, which has no security at all, besides the
initial protocol check.  To do this, you absolutely
must set up some sort of VPN.

I understand the security issues.
In fact, openvpn is already being used
to connect both of these locations.

Second, we need more information about your setup to
tell what the bandwidth requirements will be.  SD off
a digital tuner will be anywhere from 1-3mbps.  Mpeg4
off a framegrabber will be 2-4mbps.  An MPEG2 encoder
card will be 3-6mbps.  MJPEG off a framegrabber will
be 5-10mbps.

It will be SD off a PVR 350 on the backend.
There will be no live viewing, only viewing of recorded content.
Each recording will be 30 minutes or less.
