I spent the better part of Sunday on a 4 hour bus ride to Hyderabad. It was really wonderful to meet a person like Giovanni Maruzzelli who isn't afraid to roll up his sleeves and hack an idea into shape. Giovanni's talk introduced the Celliax project (see the slides of the talk) and the challenges of working with sparsely documented Asterisk and mobile phone hardware that sometimes seems to be designed by some deranged engineer ;o)
