That's interesting, although it doesn't mention the difficult case: supposing I've got an intermittent network connection with significant state on both ends, how do you re-establish a shared, sane and secure state? That's part of why I'm suspicious of the complexity of stateful connections in an ureliable (3G, WiFi) world. -- cheers, dave tweed__________________________ computer vision reasearcher: david.tw...@gmail.com "while having code so boring anyone can maintain it, use Python." -- attempted insult seen on slashdot
