@manyver_se a question I haven't been able to answer myself: if A and B connect with one method e.g. Bluetooth, will they be able to connect also via other channels once the connection is established? Or will the connection only work if A and B are connected with the same method?
@steko Yes, connections can work through various communication channels for the same pair of accounts. I am (@staltz) not sure whether it can be multiple *simultaneous* channels, but certainly non-simultaneous channels would work.
