I have a satellite Internet connection (because I have no other choice, that's why :-) which has a quota of 200 MB per day (that is not a typo).
As you can imagine, we can very easily go through that quota and end up severely throttled for the next 24 hours (starting when the quota is exceeded, even if the quota was only minutes from 'rolling over').
I am trying to figure out ways to minimize usage.
My first thought was to use something like GlimmerBlocker on the iMac (which is our media server, so it is already on 24/7), and point all of the other devices to use it as the proxy.
But I am looking for other ideas as well. I do not know of many applications out there which might be of use for this.
Technical details of the network and devices
Our household has 3 Macs (iMac, MacBook Air, MacBook) and 3 iOS devices (iPad 2, iPhone 3GS, iPod Touch [current gen]).
All of the devices except the iMac connect to the network via Wi-Fi.
(There is no 3G coverage, so the iPhone or iPad must use the Wi-Fi network.)
The network is served by an AirPort Extreme 802.11n (3rd generation) which operates in 'bridge mode' connected to the satellite modem (because the modem has to be the router and DHCP server and I cannot access those controls at all).
What are my options?
I have already 'trained' myself and my family members to avoid downloading audio or video files, but even with simple web surfing it is easy to exceed 200 MB per day. A local proxy/filter like GlimmerBlocker can block ads and other cruft we can't afford to download, but that's all I can think of.
Most of the "bandwidth monitoring" apps out there will not help because they do not differentiate between local (LAN) traffic and Internet traffic.
Can anyone think of other solutions to help minimize the pain of this daily quota?
