We just published a blog post
about using Copay on a server to host multiple wallets and have them updated. This is useful if you like to implement multiple online wallets hosted on a server like BitGo. The github fork is here
. The current version supports only 1-1 wallets but soon we will update the project to support multi-signature wallets and communicating them using the Insight mailbox plugin. Currently, every Copay wallet establishes a connection to the Insight server so it's difficult to scale if you have all the wallets in a server.
Hope it helps,
