Moxxey,
I also offer my congrats on the purchase. Hopefully your transition will go smoothly. I've addressed a few of your points below:
Multiple BeoSound 5s This isn't (and won't be) possible. It'll make sense once you have the boxes in your house, but essentially the head unit talks directly to the BeoMaster 5 (where the PowerLink ports, etc. are located). It should really be thought of as a single unit.
However! We will soon see talk of a peripheral product for just such an application. These devices will have full GUIs and controls that will eliminate the need for "blind" operation in link rooms. They will be like replacements for ML IR receivers and have been described to me as "mini BeoSound 5s." They will also be a much more cost effective solution for second rooms, as the BeoSound 5 is about 60% of the overall cost of the system.
Second Room Operation Obviously this will change with the product discussed above, but today you would be navigating in "Play Mode." This is when you move the toggle to the extreme top or bottom of the search arc and the display changes to the enlarged album cover & song info. In this mode you have the ability to move forward and backwards as though the playlist you've built is one giant CD. You can also tap into your 4 playlists and navigate them the same way, and even your "seeds" (or the 99 favorites you can store) if you're using a Beo 5.
In the next software revision you will also have Fast Forward and Rewind capability.
Connection To The Network This may not be totally correct as I'm not clear on what's wired and what's wireless, but it sounds like you have 3 zones, each with a "master" in it.
1. A BeoVision 7 & BeoLab 9s (where the BeoSound 5 will go)
2. A BeoCenter 2 & BeoLab 9s
3. A BeoSound 4 + BeoLab ?s
In this setup, you probably have one of your CD players set as a master (Audio Option 1 or 2) and one as a client (Audio Option 6). So in the office, you can press CD and play the CD you're in front of, or LINK / CD and listen to the one in the sitting room BeoCenter 2.
In order to retain access to CDs from every room, you'll keep it as the master and set the BeoSound 5 to AM : NO, that it will register as a client to one system or the other. Probably the BeoCenter 2, as it sounds like it may be the main listening environment. That will yield this result:
1. TV Room: CD/RADIO accesses the BeoCenter 2, N.MUSIC/N.RADIO accesses BeoSound 5, LINK CD accesses the BeoSound 4
2. Sitting Room: CD/RADIO accesses the BeoCenter 2, N.MUSIC/N.RADIO accesses BeoSound 5, LINK CD accesses the BeoSound 4
3. Office: CD/RADIO accesses the BeoSound 4, N.MUSIC/N.RADIO accesses BeoSound 5, LINK CD accesses the BeoCenter 2.
Hope that helps.
