Here is a release plan for future versions of cwdaemon:

0.6: add some kind of support for paddle input, like the
parallel port keyer kernel module.

I also want to look at unixcw at some stage and see if
we can benefit from this package. It has both sound-card
and pc-speaker support.

We also might want to look at supporting other architectures.
cwdaemon might work on alpha, but what about sparc, powerpc,
arm, mips, hppa, m68k, ia64 and s390?

We might be able to do this by using ioctl and the TIOCM_RTS
and TIOCM_DTR flags for the serial port (see linux/termios.h) 
and PPRDATA for the parallel port (see linux/ppdev.h).

What about hamlib integration, it already has pin switching
support for parallel/serial ports?
