The flash memory is represented under Linux as a block device driven by
the mtd driver. Therefore it behaves as a normal block device that can be
read or written to. Basically, webs does a write to that block device.
Earlier versions of the source code released by Edimax included the webs
functions. I think the source download is getting more and more useless on
every revision.

Remember that the whole ramdisk (which has data of less than 3MB) is BZIP2
compressed, and it is concatenated with the kernel and then compressed in
GZIP. That makes 450KB not-so-big in 2MB.
