i added this feature to alsa-lib cvs now.
you can create a virtual rawmidi instance with the normal
snd_rawmidi_open() call but using the name "virtual":

	snd_rawmidi_open(&input_handle, &output_handle, "virtual", 0);

then a sequencer port is opened, and the read/write access to the port
is converted from/to MIDI byte streams on this rawmidi instance.
so, basically, you don't need to change your code so much :)
of course, you cannot call read() or write() directly.  instead, use
snd_rawmidi_read() and snd_rawmidi_write().

so far, there is no default connection when it's opened.
the configuration will be extended later to allow the definition of
default connections.
