What does LightCloud add that Tokyo Tyrant does not already provide? I've read the websites of both products, it's just kind of confusing.

From some other comments, it seems I'm not the only one confused. Tokyo Cabinet+Tyrant are pretty new on the scene and there isn't a lot about them in English yet. So, if you add a level of explanation to the site that seems excessive to you, people would probably find it more useful than you expect.

LightCloud adds horizontal scaling. If you just use Tokyo Tyrant then you can only scale by buying bigger servers. If you use LightCloud you can scale by buying extra servers.

When scaling upwards you would generally _really_ want to scale horizontally, since the vertical scale has a limit and you can quickly reach it (plus, buying bigger machines is generally much more expensive than buying extra machines).

How horizontally have you scaled your systems in production? The homepage mentions 2 servers. I'm wondering if you are using it in production with more than 2.

These two servers run 3 lookup nodes and 6 storage nodes (i.e. 6 lookup nodes and 12 storage nodes in total). These servers are quite powerful [32GB of RAM and using RAID10], they also run MySQL.
