Dual funded with equal amounts? Or you mean sending LN payments as a CJ?
Entirely possible that I'm mis{sing,interpret}ing things here but: it's a shame that the dual funding in c-lightning is still behind a non-default experimental-dual-fund flag and that when i search for the "option-will-fund" in the listnodes output I only get like 5-10 out of 90K. To be clear, by following fairly simple instructions in an old blog post, I was able to make a well-funded and perfectly balanced channel, within a couple of minutes.
For those interested in coinjoin, note that this *is* coinjoin and arguably one of the best types, since by nature of the offchain payments, this kind of CJ can actually hide flows better. If we want to get the real power of such a thing we'd ideally start batching *multiple* such channel opens together, but that's putting the cart before the horse here. Dual funded channels are such an obvious good, why is it not a more widely used system, or am I missing something? #lightning

Dual funded means eg. I contribute 100k sats and my channel counterparty does as well, so that when the channel is opened, it has 200k sat capacity but is balanced, with 100k inbound and outbound.
This will likely required liquidity ads too, because your counter party won't want to provide free inbound liquidity to anyone who asks, right?
Or are you thinking to only peer with nodes that are motivated by privacy and balanced channels?
Oh yes, i certainly assume liquidity ads; it makes no sense not to include market coordination, especially considering fees are offchain :)
