Will do - Probably this afternoon.

Currently I'm setting Ardour up to use all three 1394 drives. That's
takign far longer than I hoped as I have to copy GigBytes of data
around and fix up partitions to get it to all mount and make sense. On
the good side when it's done I've calculated I'll have over 40MB/S
drive throughput. That's about double what I've had in the past.

After I wrote the earlier messages I tried running at 64/2 on this
machine. It jsut won't do it. xruns even with non-threaded operation
on the hdsp.
