For non-root applications to connect to jackd you will have to patch your 2.4
kernel (adds some security risk). The file "include/linux/capability.h"
requires a small change. If you are using a 2.6 kernel you can use the new
Linux Realtime Security module. This is all explained in the jack faq
http://jackit.sourceforge.net/docs/faq.php -- not very hard to find
