Sharing a SignalR hub between a WebApi and MVC pro

Question

Is there a recommended approach to sharing a SignalR hub across two applications?

The actual situation is a public facing WebAPI project and an internal MVC WebApp. What I'd like to do is call methods on a SignalR hub from the WebAPI project and have the results of these methods pushed to clients connected via the MVC app.

Would the best option be to create a third 'Hub' project and have both projects connect to that? If so, how are the hub instances managed? Can both applications get a reference to the same hub from distinct app pools (and possibly hosts)?

I read a little bit about GlobalHost.ConnectionManager.GetHubContext, would this suffice to get a effectively a singleton hub which both apps could use?

Any thoughts greatly appreciated.

Just setup signalr message routing through a SQL Server table. It will automatically connect all hubs using the same routing setup. Nothing else to do, it's magic.

GlobalHost.DependencyResolver.UseSqlServer(ConfigurationManager.ConnectionStrings["signalr"].ConnectionString);

You will need the following nuget package: Microsoft.AspNet.SignalR.SqlServer
