Similar technology (OpenWRT based firmware), easier to use, less privacy issues as it's not necessary to track your network usage. And completely free.
1) order an Ubiquiti Nanostation LOCO M2 (amazing reach and super sensitive antenna),
2) sign-up with them for a VPN key. This will keep your visitors traffic tunneled through their VPN. IF there is any problem with content infringement, it ends up on their network.
3) Flash the box with their OpenWRT port and install the VPN key.
I setup my box last week and and it's been running well (http://monitor.berlin.freifunk.net/host.php?h=imaginator). Nice to see users dropping on and off. The firmware also includes support for the Freifunk mesh network. I'm looking forward to adding more nodes to the neighbourhood and growing the wifi coverage.

Get started at http://config.berlin.freifunk.net/wizard/routers (disclaimer: not clear if you should/must/can be in Berlin for this to work)
Is there some international equivalent?
What I'd really like to see is a service like this that pipes guests through a VPN instead of just setting them loose on the internet directly from my connection.
Now think of going abroad, telco has their roaming partners now they can have their wifi-roaming partners.

Side-note: If you're sharing a new product/service, only having a landing page is a big negative in my view. Show me something that works. You should not have a "Get Started" button if you won't actually let me start using it...
* probably.
EDIT: welp, saw OP saying 'we'. Nevermind.
1. There are no telco partners. We directly sell to consumers.
2. Data sharing & usage is metered. You accumulate then you use it elsewhere. Its called Karma GB.
3. We are also thinking of putting up a feature that lets you enable 'free wifi' if you are a cafe/restaurant owner and you need a DIY solution for your customers. Thinking of keeping it as paid feature.
I can use any Fon router despite not being a client of a partner ISP.
I am talking about a contract that you agree to when you purchase service.
There is a significant difference between freely using something you own. vs changing how you use a service that you do not own, and have signed contracts specifying terms of use.
Most of the linux based OS will support the above packages. For others, we are yet to test.
