I like the idea of an escrow service, to mediate transactions, especially if it's trustless, as that's one of the major objectives of Bitcoin.
You mentioned a smart contract being one of your long term goals; what should users trust on till then, before putting your funds at stake one needs a certain level of assurance or some sort of collateral. Basically, why should I trust you or your website?
I am working on a multi-sig system, basically i am trying to make it as simple as possible, even for new users, it takes a lot of work but i will get there as soon as possible.
If you have any ideas on how to make it easier for users, i am open for that.
