yes... it is problem to implement both server and client side. But the
window size feature also works with PXE clients and u-boot, so I think
it is correct.
I started to implement it with transparent proxying support in mind
(e.g. translate tftp requests to http ones, or fetch cached images with
'rsync').
But when I saw the effects of windows size support, I focused on that.
