thanks, fernando... i'll try that one AFTER the big project i'm working 
on now!

however, i'm also getting the "required capabilities not available" 
message with my current working kernel (2.6.11-0.3.rdt.rhfc3.ccrma), and 
the next line says:
"capabilities: = cap_ipc_lock,cap_sys_nice,cap_sys_resource+e"

qjackctl shows "RT" after jack has started, so i'm assuming realtime 
operation is actually ok as user, but i'm wondering about that error 
message.

any clues?

thanks!
