Kaone...
It sounds like you do not have a network setup so some concepts might be unfamiliar.
The Network Accessed Storage, or NAS is completely seperate device from your desktop computer. It is a self contained hard drive or set of hard drives including network hardware and software that connects it to a network. The NAS connects to the network independantly and any computer can access all of your data files on it through the network you setup. Sonus could access this NAS independently of your computer.
I have all my music data files on NAS. Nothing is really kept on any individual computer. This seems to be the way Karimelo operates too.
That said there in no real reason to use NAS unless you are going to use multiple computers that need access to the same data files independant of each other...OR (as seems the case with Karimelo)you use the Sonus system which could access the music files on the NAS even if your computer is turned off.
If you want backup you could simply get an external hard drive and save your music files there.
------------------------------------------------------------------------------
The softwares- whether iTunes, MM, or the Sonus Desktop serve the same purpose...they are the "player". Sonos' internal control and playback system uses its own player...it cannot use MM.
MM gives much more flexibility, tagging control etc....
The two softwares should in no way cause problems for the other.
Each time you add something or change something in your actual music files you must update the "database" in the other software. The database for each software IS the "index" and vice versa...the index or database is NOT the song files themselves...is is just a software file the individual programs use to keep track of where the songs are on your hard drive.
For example...lets say you have all your music on a NAS drive and are using Sonus equipment and MM.
1). You use MM on your computer to rip a new CD, download Album art and tag it the way you like things...MM is set-up to store the music files on the NAS drive...not on your computer's hard drive.
2). Because MM ripped the file it should automatically update your MM database/library/index.
3). You must now open the Sonus Desktop and have it update its database/library/index from the new files you added to the NAS. It will check the NAS and add the newly ripped CD to its database/library/index...I believe it has an automatic "monitor" system that checks for new stuff each time it is started.
Key points:
*NAS is just a hard drive storage that is completely seperate from your computer. Sonus can access it when your computer is turned off.
*You can use MM and the Sonus software together.

The Sonus syetem seems very good...user friendly and bulletproof. I seriously considered it...the price was not as much of an issue as flexibility and usablilty.
BUT, I think you can accomplish the same thing with MM and a basic network....and end up with more flexibility... at a fraction of the cost...and if you still want to go Sonus later you can still use the wireless router ..and you can always use the Airports for printers etc....
For example...if I am understanding things correctly....
1). You could simply install a wireless router....very basic, very cheap, very usable for other applications....like wireless print server etc....(With Sonos you are actually buying and setting up a wireless network...but one that only Sonus can use)
2). Buy and set up an Apple Airport Express connected to your home stereo and and another connected to "the kitchen" sound system...all it requires is a line input.
3). Download and install the "Remote Speakers" software for MM.
4). Simply use your current computer and current MM setup to organize your music and playback to the house sound system AND the kitchen sound system. Your wife could simply use MM at your computer to playback playlists etc from MM...thats what we do here.
I don't think you could lose...setting up the network and the router and the Airports can be a pain....it would definitely be some work compared to the turnkey Sonus system....but it is really pretty basic stuff.
Did you see this?

LOL i just noticed your new post....sorry to be late....this discussion might help with some concepts anyway
