The author of the Poseideon-stack (Chris Hodges) made some
comment on amiga-news.de.
Everybody who wants to licence Poseidon may do so.
Currently this includes Highway and MorphOS (+Amithlon_2.0 ?).
He is also in contact with the guy who does OpenPCI to support PCI_USB-cards.
But he won't make the low-level-dev info fully public because he fears copy-cats
(Elbox ? :-x )
