Antoine,

Perhaps it would be an idea to write a gist or some other public facing 
page with what you need from volunteers, so it's kind of step by step?
Unlike Peter in this thread, I think most people would want/have to set up 
new nodes to do this.

You have said: Current and default installs of Core/btcd + lnd/cln/ldk . I 
know that e.g. Core has some pretty non-trivial choices but I guess we can 
stick religiously to whatever is default.

But other details like:
amount in channels - does it matter?
How many channels? Channels of specific types (thinking e.g. unannounced)
Should volunteers have channels with each other? is there any aspect of 
topology you require?
Network connectivity - I guess it's not important, but just in case worth 
mentioning, e.g. should/should not use Tor etc.

Forgive me if some of the questions are ignorant, I have not paid a ton of 
attention to the discussion around these attacks.
