ilovezfs: thanks again. It was, of course, a pleasure to work with you on this.
Anyone: there are some gaps to be filled (mostly in the FreeBSD column) and a few questions be answered.
With regard to the ZEVO Community Edition implementation, there arose a handful of OS X-specific questions that are not on the sheet. I'll seek answers. If there's anything substantive to be shared, I'll add a row to the sheet.
Thanks
Graham
