When Janus is used even if it is possible to open several data channels
with different labels and send data on them all the messages are
received in the first data channel opened.
In Talk the "status" data channel is used to send the data channel
messages, and before Janus 0.7.0 it was the first data channel opened,
so the messages were received on it.
However, since Janus 0.7.0 the data channel messages are received
instead on a data channel opened by Janus, which is named
"JanusDataChannel". It is not possible to change that behaviour on Janus
except by patching it, so for broader compatibility the messages
received in "JanusDataChannel" are treated like messages received in the
"status" data channel

When another participant shared the screen a new offer was requested.
However, the offer was requested for the video instead of for the
screen, which caused the HPB to stop the previous video connection and
replace it with a new one. As receiving new offers for an existing
connection is not properly handled the offer was applied to the existing
peer connection, which caused the new offer to be ignored and the old
peer connection to be kept (but frozen due to the HPB not sending more
data for that connection).
Requesting offers are not needed when the peer connection is a screen,
as the HPB will automatically send the offers itself. Therefore, now
offers are requested only when the connection is of "video" type.

The avatar of guests is based on their display name/nick.
When the HPB is not used the nick is provided in the offer/answer
signaling messages, and later updated through data channel messages when
it changes. When the HPB is used the nick is periodically sent through
data channel messages. Therefore the avatar is based on the nick set in
the peer connection and reloaded when the nick changes (although it is
currently a bit hacky and brittle, as it is based on whether the nick
shown in the text view changed rather than whether the nick itself
changed, but it works nevertheless).
Note that currently it is required that the guest has a peer connection
to know its nick and, therefore, its avatar; some changes would be
needed in the clients to also send the nick when there is no peer
connection.
