Thanks guys!

I understand that there are reasons for not supporting non-blocked io, but
are there any plans or work in progress regarding this? Or doesn't the
current infrastructure lend it self to this easily?
I guess it must have been discussed before. I saw some old posts about a

I am now at the cross section with the sign saying Left "lwip" Right
"commercial IP stack". :)

If I choose lwip, I guess I will have to either do some implementation
outside the socket layer, or try to help the development of lwip in the
non-blocking way.

I like the socket api, because of its portability, and almost all my
designs are a bunch of nodes that has open connections to many other,
non-blocking is crucial for me. In this design, I would use lwip with
freertos.org on an NXP arm7tdmi.
