Hi,
Ok assuming that we work on the model that if "connectionLost" is
called, i can set a flag.
But from the twisted model, in RequestAvatar, the "mind" is not set to
the instance of the protocol, so there is no way to
reference the instance of the protocol? Referencing the factory itself
is of no value since we are interested to find out the connection =
account pair.
Or is there a way to get access to the current protocol instance from
RequestAvatar?

There's no way to know; it's a race condition. If the
connection dies before authentication, then requestAvatar won't be
called. If the connection dies shortly afterward, you'll get a
connectionLost shortly after authentication, but there's no way to
predict that that's about to happen.
If the connection dies at the exact moment that authentication
occurs... well, the joke's on you, in a network of Von Neumann
architecture computers, there's no such thing as the "exact moment".
It actually died shortly afterwards, just so shortly that it seemed
simultaneous to a casual human observer. So as far as the code's
concerned, it's the same as the "shortly afterward" case.
