I think oreo is a CITES listed plant, which I think includes seed. The only way they could be sent would be to file the proper paperwork, or send plantlets in vitro. Correct me if I'm wrong, somebody.
As for the fungus problem: what causes a Sarr to crash in our conditions appears more to be a rot that attacks the rhizome, especially the older tissue away from the growing point. The disease insidiously moves forward towards the growing tips. Keeping a watchful eye on the rhizomes, especially in late summer down here (hurricane season), and frequent treatment with Cleary's 3336 or Fungo is the best remedy. We've saved plants by pulling them from the pot, even in late summer, removing the infected part of the rhizome, sealing the rhizome cut with powdered Captan and repotting with the rhizome only half buried in fresh mix. It really is good practice to keep the plants clean around the rhizome, removing dead pitcher "stumps" and debris.
Those of you living in temperate climates probably don't need to be so meticulous, but those of us living south (in the northern hemisphere) of Sarracenia habitats have got to watch out for these problems.
As for seed. It readily germinates for us down here after spending six weeks on wet peat in the refrigerator. Wish we could get the Nepenthes to respond like the Sarracenia!
