Yes indeed! That’s the one 
It’s a great read, IMO, especially considering a couple of things:
- The planning/logistics, and staffing requirements
- How BBB/Greenlight really shines in contrast to having such an assemblage of moving parts all brought together.
Others have given a positive nod to BBB and it’s capabilities in this thread too. Something of note that the recent NLnet conference availed themselves of was incorporating tmux into the mix for the workshops 
It’s hard to beat PeerTube’s automatic transcoding and VoD capabilities of presentations with livechat too, but there are some issues with many who would be presenters having to spend some time familiarizing themselves with OBS (it takes a bit to dial everything in, green screen, compression and gating on audio, etc.
@nutomic pointed out the timbre of that fediforum event, and a couple of presenters I know were less than complimentary about how it unfolded (there were no schedules - everyone just showed up and then decisions were made “democratically” as to whom would present and in which order).
He left out the (IMO) most glaring indication that, like @hamishcampbell mentioned, the organizers and general feeling was that it was folks from the #November_Rain, not particularly in tune with Fediverse history and culture or available resources in the FOSS community - and required the paying attendees and presenters to install and use privacy disrespecting, closed source proprietary software (a 3rd party skin for zoom) in order to attend.
That speaks volumes as to their previous orientation as subjugated chattel in the world of the Sunnyvale Syndrome
We had one person from Fediverse City at the time who volunteered to install that software and attend, reports back were lackluster, like people trying to figure out what kind of purpose they were trying to achieve or address. It’s s pretty good idea to know what those things are before you actually hold an event.
Fortunately, we’re all fervently committed to dogfooding here, so that’s not going to be an issue, and that is an especially refreshing thought when we’re taking about garnering EU participation - leading by example of using FOSS for delivering FOSS centric topical gatherings.
The occurrence of a sophomoric event like that, obviously completely incongruent with FOSS values and traditional Fediverse philosophy, does however indicate a deeper problem lurking beneath our waters… Outreach!
We’ve been miserably failing on that responsibility (if we’ve even chosen to accept that responsibility). It demonstrated the damage to the ActivityPub and Fediverse community caused by the double edged sword of the mastodon marketing whereby a large chunk of those November Rain folks believe that there’s such a thing as a mastodon network (there is not) and scratch their heads when you say Fediverse.
We can’t blame (well, we can) someone for wanting to, and then successfully marketing their product brand, but when it generates damage in the form of confusion it has caused we can certainly blame ourselves (as that greater community) for not effectively engaging in the kind of outreach that delivers the clarity and understanding that is needed to impart to the general public.
This conference you suggest IS NOT reinventing the wheel - it is exactly what we need at this time. Had we been performing our due diligence in this regard then that fediforum thing would have reached out to us instead of performing as if they (all three people) were in a vacuum.
And you’re right, lolz… Even as I penned that last post I was aware of the timeframe I mentioned as being overly ambitious, I was hesitant to take a good idea and say it would take longer to put together effectively - good catch there 
Well, that’s my 2¢
