For the rest I think this is a very interesting approach that we can use to introduce bitcoin without even mentioning bitcoin's name. Especially right now when the reputation is somehow dented because of the scam involving ponzi and exchangers and people start to develop the negative perception upon hearing the bitcoin's name. In a way I would say it's good to introduce the coin.
I believe using the 'ledger' aspect of Bitcoin as a sales pitch, it's a whole different product, then. Bitcoin as it is is mostly regarded as a currency, an investment, an asset, and a payment system, and maybe a backbone protocol. The latter aspect is much underrated, in my opinion, but we need actual products and services using the protocol. People don't usually care for the technology behind something, keep that in mind!
