Some questions about this feature

Content

Hi there, 
I have some question about the agent handoff feature: 
- they can be only integrate with the oracle Service cloud ? or there is a way that i can integrate it with locale custom platforme? if not, it will be in the future ?
- Is there any other richer documentation that can help in how develop it? that explain each case in the integration form ? maybe A youtube tuto or a Tech Exchange blog . 
- i don't have any idea about the Service Cloud , is the chat platform of the agent already exist? which is the product that should we provisioning to have this feature? ...
