[AG-TECH] Bridge server

[Thomas D. Uram]

Bridging an entire venue server is supported just fine in my experience.
There may be problems if the config specifies an overlapping set by,
say, specifying a venue server and individual venues on that server;
these should be regarded as mutually exclusive options and, I think,
in most practical situations, they are.
