There is a bug in the arp code. This one is _serious_. I'd recommend
nobody runs 0.99.10 on a real network - not yet anyway. There is a new
version of the networking out RSN (Linux RSN not NT RSN 8-)) which should
fix it.

The loopback device doesn't copy things flat out as it can any more. I don't
know why but I expect some nice person will fix it. It's very noticable with
things like the mpeg_player over IP and loopback. X normally uses the
unix domain loopback unless you fiddle with DISPLAY, BTW.

Join the NET channel and all will be answered (regularly 8-))
