I don't have internet access from my cell phone, so I wish I had this:
an option where you send the coordinates of two points from the map using sms (gnokii lib) and receive the route (driving directions) in a sms.

my prepaid t-mobile phone can send a sms to an email address. a small application will sit on the home desktop reading the emails (sms), then will query gnuite's gpx cgi and then send back the xml file as an attachment to a sms.

I will build the "server" which will sit on the home computer if somebody makes the modifications for the maemo-mapper.
