There are interesting parallels in the considerations in this article calling for a Neo-Pagan Seminary to the one's that have been bouncing around the Gnostic community. Not surprising, since there is over-lap, and a large portion of those coming to Gnosticism have had previous associations with the Neo-Pagan community.
I offer this for consideration, I like to look at similarities whenever possible, and such do not remove the differences. In this case the differences are quite deep, and I would place the proposed Neo-Pagan Seminary much closer to the mainstream ones than to the Seminary in the works at the Gnosis Institute. (So please, at least wear a hard-hat when jumping to conclusions.)
