Audio Systems: Wireless speakers, sonus system, crutchfield

Question
Hi. I just moved into a house that has 4 built-in (wired) speakers in the living room and 2 speakers outside in the deck. The wires for all 6 speakers come out of an outlet that is located exactly on the other side of where i want the TV/receiver to be (I'm planning to buy an AV tuner once i figure that one out).
My question is:  In order to connect the 4 speakers in the living room I need a wireless solution. Any ideas on that? I'm looking for something that will support all 4 speakers.
Second question: Will this solution support multi-zone #i think that's the right name - i want to play different music/sound in the living room than in the deck where the other 2 speakers are).
Will appreciate and ideas/recommendations.
Many thanks and happy holidays.

Answer
The Sonus system is quite elaborate and will do lots of things including giving you control in different locations of the house:

Crutchfield.com has some products that may give you some ideas:

Panasonic has a wireless home system that may still be available in some stores:

And Sony, too:

In most of these systems you must use the output of their receiver to feed into an amplifier to drive the speaker systems in the room.

Does this give you some ideas of how to strategize a solution?  Hope so.
