OK, but as an Activity author I might like to specify that cap at runtime,
depending on many things, such as the size of the document.  I might even
want to let the initiator choose the number of participants.  I think we
should also have a runtime API, so that the cap that can be varied at any
time.

In fact, it might be nice to have a a generic solution for defining config
variables that can be controlled either statically or at runtime.  We have
mentioned a wide variety of such variables, including things like whether
screen rotation is supported.

I don't see why any Activity should be excluded from such VNC sharing,
regardless of max_participants.
