@dlanor: all clear to start network support implementation. I've made some changes, so you can reuse existing stuff (directory listing, for example). There's also an icon for 'netfs' . Most challenging part (I think) is handling device connect/disconnect (if, for example, server dies, of started after SMS). I also suspect, that using fileXio for 'host' is very slow, so, I've provided a mechanism to switch between 'fileio' and 'fileXio': take a look at FileContext.h/.c. Good luck !
@all: I'm going to take some break with further development now (thinking of the best solution for CD/DVD support at the same time). When I'll be ready I'll annoy someone with modchip to launch countless test programs .
