I as someone who follows the Morphix project closely I really don't remember them offering the multi-session feature in quite the same way as Puppy does.
See your other post for my reaction on how you are choosing to use my board.
I don't know what Morphix achieved -- it could have been something really primitive.
Anyway, to placate Morphix people, I will be uploading an updated Unleashed page soon with a mention that Morphix was first.
