[kronolith] SMS reminders with Kronolith

[Sebastian Arcus]

As far as I gather, this is not an existing feature - but has anybody 
attempted to integrate Kronolith with some kind of SMS reminders - maybe 
some hooks to work with Gammu, or something similar? I have a site where 
they need sms reminders for appointments, and it would be nice to 
integrate it with Horde/Kronolith, instead have having a completely 
separate system.

Any suggestions are welcome.
