We've been testing on TestNet with Bitcoin and Litecoin since May and we're ready to open our doors for sign-ups.. Source (http://www.reddit.com/r/Bitcoin/comments/1c7u0k/new_btcltcppcnmd_exchange_toronto_bitcoin/)
Should mention that you will not be able to see any orders unless verified, however we're working on this now as it just doesn't make sense!
We have also created an API and it is available for use once you are verified. The documentation can be found here: https://vaultofsatoshi.com/api
