I think you should amend your poll options to allow for doing it so as not to interfere with other work talking place, such as getting the UI / UX in better shape so it's more attractive to traders and easy to use for all.
I'm happy to see the progress is moving right along, thanks to the efforts of Jakub & Bill Buttler, an of course the devs doing the actual work.
I have read the papers on Vuvuzela and think this is an excellent candidate to extend our ecosystem. Perhaps it could be adapted for use with web servers for truly anonymous browsing, which if that can be done provides another layer of security for web wallets,
In general I'm in favor of using this technology, but it should not impact efforts currently underway. An FBA could accomplish that if devs other than the core devs or those already working to complete current efforts, were recruited or found to do this work.
Realistically, I'm not sure it's reasonable to expect that such an FBA would not have some impact on current efforts, if nothing else discussion about API and code to integrate this new feature. Without more examples, tutorials and documentation efforts like this cannot be purely independent.
