Got mine today! Thanks!
Here's what I did, in case I have success.
I took four of those plastic trays your grocery store's bakery typically puts things like croissants in (like
this; square, about one square foot). I used 50/50 peat/perlite, rinsed everything really well, then nuked the media in the microwave for two minutes (at about an inch deep). Let the media cool, then put it into the trays about an inch to an inch and a half deep; one tray per species. Made sure the media was nice and damp, sprinkled the seed on the media, closed the lids, then put the trays in my rack. We'll see how it goes!
