How are things with tty? One question that came up -- what sort of SoCs are you targeting? A number of people are insisting that smartphone SoCs with 256M DRAM are the minimal systems of the future. This seems unlikely to me, given the potential for extremely cheap SoCs with EDRAM or some such, but figured I should ask what you are targeting. Thanx, Paul
