Like band - see band, everything else is pointlessness at this point. There is no industry, there's no money, there's very few opertunities for bands to do anything unless it's completely DIY.
I would like to see all the DIY bands in dublin throw in the fee to be considered for HWCH per man (so say it's € 25 at average 4 members per band and 100 bands playing that's €10,000 to hire venues publicity etc) and organise a festival where there own bands played and there was no fannying about expecting David Geffen or whoever the fuck is in charge of the "the industry" now to show up.
Call it Meh fest. Spend the money hiring Joanna Newsome to headline.
In fairness to Das Nugs, he's one of the founders of Popical Island and its all-dayers are essentially what you just described.
