not sure why OP is fascinated by coinbase but thats where PepsiCo/Ebay should make a webwallet service
imagine it. people put $30 worth of bitcoins into a pepsi-co stored wallet. and this gets confirmed to credit the customer. now the customer can use those funds within all pepsi brands and partnerships. so this includes vending machines and........ starbucks. now imagine the other big umbrella corporations. ebay (ofcourse is coming soon, well before pepsi. because at this moment i don't think pepsi even knows about bitcoin).
or imagine a phone app that you deposit into and it auto-sends 'offchain' to these corporations via well established corporations.
these idea's including the OP's idea of multisig have been thought up many times over the last couple years, we just have to wait for the corporations to accept, adopt and use them in combination

When was this idea released!? This definitely sounds like a great idea. I myself have had trouble having to wait for confirmations before I can receive products or services.
