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. Enrico
