Preparing a filesystemblock with files inside should be not a big problem...
Testing can be done by downloading (sending ascii) like today and when
finished, prepare the filesystem and download the separate image.
When operating system and filesystem are different partitions it would be nice.
How big is the real nesseccary os-image currently ? A small area (32-64kB) for
filesystem should be enough for most of lua applications :D
