This looks like a great option, and a welcome addition to a previously-underserved market. As 10GBE becomes more readily available, more people will want to build for it at a lower-than-$1k/port price. I'm looking forward to trying one of these out very soon. :)

Five years ago I was buying 10GBase-T ports on Dell servers, and even my Dell sales team couldn't tell me what to attach them to. What a long, strange trip it's been.
