Hi,

Doing a SMS gateway with perl or gnokii is really easy. Even Gnokii can have a look in a SQL database to get the data to send to sms.

The main problem is "IP SMS" gateway there is on the network. I understand observium team, and really using plain SMTP with 
small messages can be better to be done than adding an extra code.

Regards
