While we are on the topic of random feature requests...
one thing would personally find quiet useful for LuaSocket
to provide is standard io library compatibility layer...
if such socket.io package existed, one could swap it
seamlessly with the standard file based io library and
pretty much turn any regular Lua code into a network
Non-trivial to do portably. Sockets are not files. Socket fds and file fds
can mostly be interchanged under UNIX/Linux, but not on all OSes, notably
Windows and Windows-derived OSes (e.g. WinCE). Under Windows, file I/O and
socket I/O are just, well, different...
Of course, you can wrap Windows to look and behave in a Linux/UNIXy
fashion, but not in any compact, simple or secure fashion (Cygwin, QED.)
This is why an astonishingly useful tool like socat:
isn't easy at all to port to Windows -- the only known Windows version
requires Cygwin, which isn't a port in any reasonable sense. (And look at
home much extra code is needed in netcat to make the "-l -e" option work
under Windows, compared to under Unix, though this also comes down to
the lack of fork() under Windows.)
KISS says to have a core file I/O library, and an "add-on" socket I/O
