I'm not sure about AcidX, but there is only a handful of coders who is stil working on a HB server to actually blow HBOly off.
Bruno spends years coding with help from other hired coders to bring what you see in Oly now.
Gerion is working on Portal, and Michal is working on Rocks.
Everyone is trying to achieve what Bruno has done via the client ddraw. I really do hope someone from the kindness of their heart to release a source that helps everyone.
