It's a bit old but I have some questions to it:

"MorphOS already comes with all stuff needed to create/read PDF files "

which stuff is this to create PDF files?

"But since NetStack/drivers do not support MultiCast, this is currently impossible anyway. MultiCast requires more work to implement, so it won´t be there soonish."

Is this still the case or has it changed since https://morph.zone/modules/newbb_plus/viewtopic.php?forum=32&topic_id=9037&post_id=98641&viewmode=flat&sortorder=0&showonepost=1?
