Comment(by datallah):

 I just added a new version of the patch with the following changes:
  * resolving a buddy only occurs for the protocol that we received a
 presence notification on
  * IPv6 buddy IPs are preferred to IPv4 IPs
   * if there are multiples of either protocol, the one (within the
 protocol) that actually gets used continues to be arbitrary
  * Update the file transfer code to support IPv6
   * I don't believe that the core purple_network_listen code is doing the
 right thing yet, but if it does, then bonjour file transfers *should*
 work.
