eSMSd is a simple daemon for connecting a Gnokii-handled mobile phone with SQL database into a SMS gateway. It bears great simplicity, and is therefore suitable for custom projects and smaller businesses, but is still powerful enough to handle larger loads. The project is intended as a replacement for Gnokii's SMSd, but is much simpler (therefore great for hacking, learning, and SMS magic) and also a little more portable (SMSd tends to crash on AMD-64).
