+1.
If the modifications needed to accommodate Lightning Network (LN) were implemented now, it would be possible to evaluate its utility for scalable, low fee transactions. Something like LN or sidechains will be needed sooner or later anyway: now, if we stick with core, or in 2 years with classic.
@btcbug - I think that it is a more urgent issue that LN be implemented, as opposed to debating block sizes. 1MB, 2MB - either way you have slow confirmations and malleable fees. LN would really address actually real debate: payment vs settlement, so that it can be evaluated by users for scalability and performance.
Bitcoin is a settlement layer since it's the nr1 currency, and it has intrinsic value as the nr1 crypto currency.
It's also a commodity and as a settlement layer like gold in a vault backing paper money (but one that is actually transparent and 100% backed and not a ponzi scheme)
So yes, bitcoin is more a commodity money like gold, which needs a separate faster payment system, because obviously 10 min confirm time is not meant for it.
