yet. We have looked at it and our architecture in Jetty-9 should be
able to handle it reasonably well, but the main issue is the support for
TLS extensions is not yet in the JVMs.
We could do a similar approach to what we have done for
NPN/SPDY, but have not yet done so.
If this is something
that you'd like sooner rather than later, then please contact us and we
can discuss the possibility of accelerating support for it.
