Ask HN: How will vendors connect to the Lightning Network?

I asked this on r/bitcoin yesterday, but nobody had an answer: I understand how buyers will connect to the Lightning Network. They will open a channel with another node and fund it with bitcoins. If they put in 1 btc, they now can spend up to 1 btc via LN. But how will vendors connect so that they can receive money? How will they convince some other node to fund a channel with them?
