just tried it with a EXT3 boot version of 1.03.49 live 0.4.7.3
ran through telnet (putty), and getting "invalid character!" answers
it doesn't seem fast either
connected through lan (WDTV) and wlan (putty)
tested input in search window of Youtube (video)
it would be a nice feature still....
edit: this boot version runs from 1.02.21 flashed WDLXTV. Maybe it runs slow because it runs from usb instead of flash ?
