+3.2 - Getting 2 input and/or output interfaces in Jack
+------------------------------------------------------
+
+As you can see, starting the Jack server this way will only enable 1 stereo
+input (Di or Ai) and 1 stereo output (Ao or Do).
+
+This is due to the following restrictions:
+* Jack can only open one capture device and one playback device at a time
+* The Audiophile USB is seen as 2 (or three) Alsa devices: hw:1,0, hw:1,1
+  (and optionally hw:1,2)
+If you want to get Ai+Di and/or Ao+Do support with Jack, you would need to
+combine the Alsa devices into one logical "complex" device.
+
+If you want to give it a try, I recommend reading the information from
+this page: http://www.sound-man.co.uk/linuxaudio/ice1712multi.html
+It is related to another device (ice1712) but can be adapted to suit
+the Audiophile USB.
+
+Enabling multiple Audiophile USB interfaces for Jackd will certainly require:
+* patching Jack with the previously mentioned "Big Endian" patch
+* patching Jackd with the MMAP_COMPLEX patch (see the ice1712 page)
+* patching the alsa-lib/src/pcm/pcm_multi.c file (see the ice1712 page)
+* define a multi device (combination of hw:1,0 and hw:1,1) in your .asoundrc
+  file 
+* start jackd with this device
+
+I had no success in testing this for now, but this may be due to my OS
+configuration. If you have any success with this kind of setup, please
+drop me an email.

+         * the address space, but end 0 and ceiling 0 refer to the top
+         * Comparisons need to use "end - 1" and "ceiling - 1" (though
+         * that end 0 case should be mythical).
+         *
+         * Wherever addr is brought up or ceiling brought down, we
+         * must be careful to reject "the opposite 0" before it
+         * confuses the subsequent tests.  But what about where end is
+         * brought down by HUGEPD_SIZE below? no, end can't go down to
+         * 0 there.
+         *
+         * Whereas we round start (addr) and ceiling down, by different
+         * masks at different levels, in order to test whether a table
+         * now has no other vmas using it, so can be freed, we don't

+        split, instead of the customary 3G/1G.

+        Note that to enable such a host
