Answer 1

Your approach does work, however the correct approach is to use the built in API: Clients.Others.addMessage(message). Also there's no need to get the hub context inside the hub itself. You can always access the current connection ID via Context.ConnectionId or send message sto clients via Clients.All.foo();

And you cannot set the ConnectinoID programatically. If you'd like to track users across pages maintain a list of users on your server and then just re-assign the connection id's as they navigate through the site.

Here's a post explaining the tracking of users: SignalR 1.0 beta connection factory

Answer 2

If you're sending the message in a method on the Hub class, you can also use Clients.Others to exclude the calling client. You only need to use AllExcept(id) if you're not in a hub method.
