Having reviewed the various bundle proposals I don't believe enough attention has been made to issues around using bundle with ICE and especially some of the more complex ICE scenarios to verify that they will work or are optimal in these cases.

For example there is no analysis of the following issues:

1. IPV6 / Dual Stack environments where it is necessary to generate candidates for multiple address families. 

2. Scenarios involving Server Reflexive, Relayed Candidates, and TCP Candidates are required.

Some of these scenarios relate to scenarios involving NAT's & Firewalls which we have started to analyse in http://tools.ietf.org/html/draft-hutton-rtcweb-nat-firewall-considerations-00. 

I intend to do some further analysis and look more closely at bundle in the context of these scenarios over the next couple of weeks but personally until this is done I cannot say whether the current bundle proposals meet our needs.
