[BBLISA] anybody doing IPv6 for real operations?/possible presentation topic

[Bill Bogstad]

The latest projections that I've read are that the address registries
will run out of IPv4 addresses for new allocations sometime in 2011 or
2012.
To my mind, this is uncomfortably close in time.    At last night's
meeting, I asked if anyone was using IPv6 for internal operations as a
way
to get comfortable with the the issues and feel like I basically got
no positive responses.   So, I would like to ask the list as a whole:

Is there anyone who has IPv6 running on their internal networks?
Are you using it for real operations or is this just for fun?
What issues with apps/server software/routers/network appliances did
you run into?
What (if anything) have you done to get IPv6 connectivity to the outside world?

I would love to have someone give a presentation on this general
topic, but I think even a roundtable presentation by people with
actual experience would be valuable.

Thanks,
Bill Bogstad
