The new version is really worth checking out!
It finally boots from USB-Flashdisk (has to be formatted as SFS-RDB, though; there's still no full support for FAT-formatted ones).
Booting time is still impressive on Efika's slow USB 1.1, but check it out for yourselves...
And oh, write some feedback to the author, it's important! :)
