Any way to deploy HA to the following RD Architecture?

Hi

I have a 2-node physical servers architecture intended for remoteapp and web access which consist of:

1.- RD Session Host, RD Licensing Server, RD Web Access

2.- RD Session Host, RD Connection Broker

-These are physically separated

-Both are Windows 2008 R2 Enterprise

We need to deploy HA. I've found this guide so far http://technet.microsoft.com/en-us/library/ff686148(v=ws.10).aspx

Which happens to be intented for Virtual Desktop. Can this be used for my solution aswell? Is it possible to do so even if they are physically separated nodes, or bring node 2 to site 1 (they are blades) and do replica site in site 2? (Windows 2012 is not an option)

Thanks in advance.
