 Sure, this patch wasn't proposed for inclusion, just attached it for
 reference when we get to actually implement this feature.

 > - You should use the new Requests API. Something like that:

 connection[CONNECTION_INTERFACE_REQUESTS].EnsureChannel(
 > CHANNEL_INTERFACE + ".ChannelType": CHANNEL_TYPE_CONTACT_LIST,
 > CHANNEL_INTERFACE + ".TargetHandleType": CONNECTION_HANDLE_TYPE_LIST,
 > CHANNEL_INTERFACE + ".TargetID": 'subscribe')

 > So you don't need to request the subscribe handle any more.

 Maybe that should be done once the contact accepted your request but we
 can start like that for now.

 That's good to know, thanks!

 should be done to properly manager buddy subscriptions.

 That's good info, will enter individual tickets for the smaller pieces.
