Its very possible to as I have 4 servers running here that I can access without issues from my clients. I was able to do it when I was running Vail and so it stands to reason why not with WHS 2011RC.
You can even get Remote Access to work if you want but you will need to have your router reserve IP numbers for each of the servers your running so their IP numbers do not change and it can be done on the server end but its much easier to do it within the router. You will need to manipulate port 443. On one server I have it set to use 443 exclusively but on the other I use External Port 444 to Internal Port 443 to make remote access possible. The only thing you need to do to access the server with 444 to 443 is to add :444 at the end of the servers remote access address. On that server you will get warnings about remote access not working right but you can test it out to confirm its working or not.
I took it abit further in that I added links to my servers landing page for each server using my primary server as a traffic cop so to speak but I also removed the LOGON Button because it caused some issues with going to the wrong server. Each server would need to have its own domain and I have 2 Windows Live Domains, I got one for WHS v1 and they allowed me a 2nd for Vail but I am not certain they will do the same for WHS 2011RC or not. I also have a couple TZO domains one of which is a Custom Domain which I do like very much because I do not like long Addresses. So I use my custome domain to point me to my primary servers landing page then I added a link to the other server and to avoid certificate issues I remove the LOGON Button.
Anyway you do not need to muck around with your landing page but if you chose to do so then an old Add-In for WHS v1 called WHiiST will help you out. On your EX485 the default page address if you look at the address bar is /HPHome but if you change that to /Home you will see the default WHS Landing Page I am refering to. But if your able to setup remote access and manipulate port 443 then all you need to do is add :444 to the servers address which you assigned External Port 444 to Internal Port 443 and it will work.
Below is an example of what I mean:
https://your server.homeserver.com:444/remote
Hope this helps....
