My efforts along these lines can be found here: https://github.com/Wiladams/TINN

My particular focus is on Windows, rather than Linux, but the Windows specifics 
are fairly isolated.  The lowest level of socket calls use a couple of Windows 
extensions.  I am fairly isolated from that lowest level because all the upper 
level stuff uses a "NetStream" class.

If I were to do a UNIX version, I would definitely use ljsyscall, because I've 
effectively created a similar thing for Windows.

As for fend, that's a great project, and could probably benefit from leveraging 
ljsyscall for most of the low level stuff.  One of the greatest things I see in 
fend is the OpenSSL interop layer.  That's a beast of a thing to create, and 
there it is.  Noone else should have to create that, and it should just become 
a standard component.  Perhaps I'll create a module to go with my TINN 
environment, and that would take care of SSL/TLS, although it does rely on 
OpenSSL, and not platform specifics (for Windows).

Picking a fairly efficient http parser would be next on my list at the higher 
levels.  LuaSocket is passable, http_parser is quite functional, but is 'C'.  
My own is pure Lua, as are a few others.  Having a standard one of these would 
be great as well.

That would just leave the development of a great event loop.  Perhaps someone 
who's used to doing massively multiplayer games would volunteer such a thing.
