Can i send audio to two or more amps over bluetooth and would the latency be a problem?
What is considered a normal maximal distance?
I want to build several small sound system and be able to transmit sound to all of them at the same time using a smartphone. Wireless 🙂

You can't do this with BT as it uses a protocol with a unique MAC address for each receiver - that is how they pair up so that you don't get someone else's phone Tx in vincinity.
What you want is a low power radio transmitter (possibly digital rf) that has no pairing involved.
You want something like this and use a BT output to feed into this so that your phone can transmit to multiple speakers.

You can also use these clever little things.

Or you can attach all your speakers to the wireless network. Use a VS1053, wifly adapter with a microcontroller in each speaker to setup to receive a compressed audio stream. The audio stream can be received over UDP datagrams.
The android device can be setup to transmit an audio stream via the wifi across the network to multiple devices. This is the way to do it outside of a custom transmitter/receiver. This is of course, if you want to write your own audio streaming app.
To use pandora or something of that nature, then you would need some type of analog to digital converter to be compatible or other "man in the middle" box. bluetooth A2DP, or something.
The other way to do it, is setup 2 A2DP devices per speaker. one to recieve, one to transmit. and do a daisy-chain style link to all the speakers BUT latency would be a huge issue. as the A2DP transmitter has to convert the analog audio into digital, compress, and transmit it. That adds delay, the delay would grow exponentially the more "repeaters" you have in the path.

Thanks for the inputs!
I like the i2i device because it seams easy to use, but the range is limited to ~10 m. The WA-321 system is too expansive. Will take a look into the WiFly setup.
Got a fm transmitter, but the signal is not very stable. Maybe it can be modded?
