Hi Maiko,

Where I work we still use X25 and SDLC for our ATM machines. Not an 
easily routable thing but nevertheless it works in ATMs that in remote 
villages all over Greece (1400 of them).

Good points and ideas that hounded me and some other radio amateurs for 
a long time but unfortunatelly there are not as many that use TCP/IP over 
AX25 today in my country. Many still use AX25 but what you are suggesting 
might boost radio ham's interest if implemented properly.

I am very interested in it for starters.

Keep up the good work and positive thoughts of yours.
