There is a sample mesh protocol available on the nRF51 at https://github.com/NordicSemiconductor/nRF51-ble-bcast-mesh , this can be used to enhance your understanding of the mesh with BTLE. Feel free to contribute and comment.

As Marc says, this should be possible to do on an nRF51822, but we don't have any mesh protocol examples for it, so this is something you'd have to make yourself. Making a mesh protocol can be a complicated task, but should be doable.

An option if you need to avoid the disruption on the BLE link could be to use the nRF51922, which is capable of keeping a BLE connection while doing ANT data transfers. ANT is also not a mesh protocol, but would make it possible to make simple networks relaying information.

Yes, entirely possible with the '51822.

A couple of comments:

(1) Don't underestimate how hard it can be to implement your own mesh networking protocol! (2) You will "reset" the BLE connection every time you take over the radio for your own protocol.
