Putting XFS on a singe RAID1 pair, as you seem to be describing above for the multiple "thin" node case, and hitting one node with parallel writes to multiple user mail dirs, you'll get less performance than EXT3/4 on that mirror pair--possibly less than half, depending on the size of the disks

No, but I can help you with any questions if you want to try implementing it, and even finish it if you get at least the basic index/search functionality working. You can use v2.1's fts-lucene as a start. That sounds like a great deal to me! I'm glad you're still interested enough in it.
