Though some of us are using TAHI I do not believe the project itself
is going for the Logo Program.

I am working on IPv6 and IPSec and using TAHI regularly.

I don't believe that you need to run your own RA.  TAHI is usually
self contained.

You shoudl check if this "just works" without the RA.

I have not heard of this and don't have that hardware so can't check
it.
