Hi Marco,

I didn't know of the guidelines until I read your mail. :)

I like requirement No. 1 "It must be easy to write safe network programs".
Problem with lots of socket libraries is that the user must know a lot of
how networks work.

If you like to send me your socket library I'll have a look at it.

Don't know. It's probably only an example - at least this says the line
above the paragraph.
