On the subject of input devices, I had a recent project that may be
just up your alley. First, I changed my xorg.conf to only read from
one specific mouse device, then I used the input event interface that
the kernel creates for each extra mouse, and wrote a c program that
mapped five mice.....(contd)

Programs that use /dev/dsp
and read from the tty can't play together so easily, and are in the
long run difficult to compose and perform with (I no longer consider
any of them worth my time). Selfishly, I lament the time others spend
working on such projects that do so much less to benefit me than they
could. You of course don't owe me anything, so this is a request
rather than a demand.
