It may be prudent to allocate some development resources to build an Electrum wallet for Dnotes, as with many other currencies. In that way we can offer a lightweight client for the majority of cryptocurrency users who prefer to manage their own wallets locally, without ever having to download the blockchain. Storing everything in the guaranteed vault is ideal for long-term storage, but for day-to-day usage people will want to have a local client that doesn't need burdonsome syncing. Electrum is perfect for this, and the platform is fairly easy to adopt.
