Well, IMHO stdin may be no a good way to communicate with dwm...but
it's the only available so far. It was for status info...because there
isn't any other needs.
I'll make it more consistent. What I really wanted is: "tag: music
-dev -log" and "status: hello world" and even "view: editor1 editor2
editor7 im music" but requires some more time.

Yeah. Never pretended to go main. But without a run-time communication
mechanism dwm is quite static (for my needs, I mean) There should be a
way to talk with it, simple and small, without reaching wmii
complexity. Stdin? Piped files? Telnet? ...?

Don't take it very seriously, but an array of pipes will do the trick
typedef struct {
    const char *file;
    void (*func)(Arg *arg);
} Pipe;

Pipe pipeline[] = {
{ "-", modstatus},

Main dwm may define and use only the status pipe while some other user can have
Pipe pipeline[] = {
{ "-", modstatus},
{"~/.dwm/tagpipe, modtags},
{"~/.dwm/rulepipe, modrules},

Main dwm should provide the basic loop to open every pipe and call the
associated function when there is something to read.

Thanks for the hint.
