All
I've not finished my experiments yet but posted the below on NS so thought it may be of interest to those of you using Mac Mini's as slaves.
Interestingly for those who prefer RAX to Bidule and can get it to work without interrupts (see below) I managed to get 8 returns back to the main DAW by using Wormhole in the 8 Send Slots and then adjusting the RAX send levels to each wormhole.
Sorry if it's confusing I'll try and put up a decent tutorial or something once the 3rd mini arrives. Then again if it doesn't work with 3 minis....

Hi Bloggs
Once I get the 3rd Mini up and working I'll post up a tutorial or something more detailed. In the interim, the setup is like this:
Intel MacPro (Main DAW) running MoL (MidiOverLan) through gigabit switch to mac mini's.
Each Mini and the DAW then runs Wormhole to stream the audio back. I have used both the internal soundcard (muted) and an Edirol UA1EX as the sound device and get similar results with both. The 3rd Mini will not use a UA1EX as I am confident that the internal audio device on the mini's is sufficientty low in terms of latency I don't need to waste the money on buying a seperate audio interface.
Each Mini has been modified and holds a 7200 RPM Hitachi 100GB HD and the VI samples are kept on Lacie Mini FW400 drives (250GB).
Each Mini runs at 256 samples and uses Plogue Bidule as the host. I then use the VST version of the Vienna Instruments (rather than the AU version) as it seems a little more responsive. I did use RAX originally but found it had some bizzare streaming problems (notes cutting out during the sustained portions). I have attributed this to the AU version of the VI but haven't done sufficient tests to prove this.
The DAW also runs at 256 samples (about 6ms) with the RME Fireface 800 and Wormhole is set to a latency of 600 samples on all devices and is synced.
Each Mini runs 6 VI VSTs (at least) and I have currently been happy enough to have 3 instances of Wormhole per mini (so 6 on the Host, 9 when the 3rd Mini arrives). This gives me three paris of stereo return channels back to the main DAW. Which I then can then pan independently and set various levels of reverb.
So far I have not had any noticeable latency and can happily play live if I need to.
I am using Cubase 4 on the main DAW and when AudioEase release a compatiable version of AltiVerb plan on using that for reverb - at the moment I am using Cubase RoomVerb (not ideal but workable).
Hope this is of interest.
Cheers
