Martin,

Enjoy the Geeksters shows.  Here is a possible alternative for you for your client where you need DNS control.

Check out the TP-LINK TL-ER6020

I posted your question their their technical support team:
I am wondering if there is a way to provide DNS filtering from this router.
What I am looking forward (I believe) is a way to block port 53 from my Internal LAN so that Internet clients cannot pull DNS information from the WAN side of the Internet.
Here is what I am trying to accomplish…
1. This is a shared Internet area with WiFi. I do not have control over the individual computers connecting.
2. We use corporate OpenDNS to filter access to sites which works great.
3. What I am want to do is eliminate the possibility of someone being able to manually enter a DNS on their individual system and bypass the OpenDNS filtering.
Is this possible on a TL-ER6020?

Here is there response:
Dear John,
Thank you for choosing TP-LINK, This is Catherine from TP-LINK Technical Support.
From your description, i think what you need is to block the clients who use other DNS to access the internet.
So you can refer to the function ‘Access rule’.
You need setup two rules for LAN.
First one, Allow the destination(DNS you want) from LAN to Any Source.
Second one, block Any destination from LAN to any source.

Hope this helps.  The router is under $150.  AmazonLink:

Hi folks, I remember a geekster episode where Martin mentioned wanting to use
Open-Mesh to solve a particular issue. I came across another interesting
alternative that more or less competes with it. Its called Mesh
Potato:(http://villagetelco.org/mesh-potato/) which allows people to create
their own mesh network to share both voice and data and requires relatively
little configuration according to what I understood from the site. Its also
has the benefit of allowing you to connect a normal land-line phone to the
device allowing users to create their own Voip systems.

I was wondering if anyone has used this in the field, and if so what are
their thoughts.

There is also an Ars Technica article dated 28 August 2012, that provides
some background to why the device was created in the first place:
