Hello, yes, you're right, the system still does not support Maemo, but this is a possible future development for EGNOS. Also, just for you info, I've found the following info on Egnos Portal regarding Maemo:

''The PEGASE team has developed a toolkit that applies EGNOS corrections on Nokia Maemo phones using the EGNOS corrections from EDAS and without the need of an external GNSS receiver. PEGASE also has an additional application called "EDAS proxy" which extracts only the data that are necessary for the EGNOS application from the EDAS data flow and makes them available on the Internet in the SISNeT format.''

Not sure if you can use this info though.
Cheers,
Leonardo
