I have yet find an answer to your question, my friend. It seems that even PvPGN has no idea. That software is geared towards Warcraft 3, D2 while it supports D1, SC and more. I think the unofficial answer would be no. I would imagine it would mean someone would have to extract the Battle.net client from Diablo 1.04. Did they have Battle.net at 1.04? Maybe someone could rewrite the Battle.net client to work with PvPGN...
I think for multiplayer on Hellfire, best bet is Tunngle.
