I think Elbox probably locked the drivers to the USB card because they and many dealers didn't make a penny on the graphics, sound and network cards that people bought for their Mediators.
I think Chris Hodges' decision to pull support for Spider owners was something that came out of the "RDB trashing code row", so when I posted about cracking Poseiden, it was supposed to be ironic.
I try to support Amiga developers where I can. Buying/registering products and making donations here and there.
If Chris would let Spider owners register Poseiden I'd probably get a Spider and then he could have some of my money too.
