Just small notice, SyncIt Group Company is near to finish the emc2 C2C store. We are hoping to have pre-release version at the end of the week.  The demo page is currently on this address http://4you.emc2.syncitgroup.com/ For the start, payment will be available through PayPal and when we get API and wallet, we'll develop Magento extension for public use and implement it in our store.
