I developed this using a Raspberry Pi and it works pretty smoothly. The only catch is that the first time you look up a public key/easy key it may take a while to look up the balance and build the balance index. After that, it should be able to calculate the balance pretty quickly. So be patient in the beginning.
I only allow the saving of easy keys. Afterall, who can read a public key with font size 3? The only drawback is that you may lose some privacy because all your server keys would be registered with the easy key service.
