I do, but it's not normally advised.  A kernel with "capabilities patch" is 
supposed to alleviate the requirement to run as root in order to gain 
real-time scheduling priority or whatever it is you gain by running as root. 
  I am going to begin trying to run Ardour as non-root and see how it goes...

I am eagerly anticipating the answer to this question...  as this is a major 
irritation for me!!  I mean, you get the "static" mix nearly perfect, need a 
touch of automation for a fade out or solo or whatever, and suddenly your 
whole baseline mix is blown.

I use TAP Dynamics all the time with my quasi-opto curves.  It works, but 
it's not as good as my vst favorite:  Blockfish!!  The whole "fish filets" 
suite (Blockfish, Floorfish and Spitfish) are fantastic, and so are the 
other stuff from digital fish phones such as THD, endorphin, etc.  Freeverb 
(VST version) is also great.  I really love that stuff and miss it dearly on 
Ardour.  Ardour won't build on my system with vst support (won't build for 
source at all and it's way too much trouble for me to spend any more time 
figuring out why), so I don't use these anymore since switching to Linux. 
The lack of access to these critical plugins is almost enough for me to 
switch back to Windows, at least to mix.  It's like making near and dear 
pieces of audio recording equipment suddenly unusable...

If anyone knows of a binary RPM for FC1 of beta19 or later with vst support 
in it, I'm all ears!  Will the Mandrake rpm work?  I'm dying over here!  ;) 
  The Planet CCRMA build does not have VST support...

I'm using Delta 1010...  similar enough...  24/44.1, realtime, and whatever 
combo of buffers & etc. that results in 93ms of latency works for me.  I 
don't mind more latency but Jack won't start with higher settings.  No point 
in lower latency with the monitor mixer feature of the Delta cards.
