Hello Steve,

Sorry to disturb you again. I still have some more questions

1.Do you have any localization support for event service? Like catalog
support.
2.Do you have any performance data related to Event Service? 
3.Any inbuilt security for distributed event service or it is assumed
that the event service will operate with in restricted network area? 
4. Can you name some of the commercial vendors from whom we can buy
support for OpenAIS?

Note that I read some info on these topics on the web , still I want to
make sure I am aligned and understood properly . 

Regards
Ramesh

Commercial support is available from various commercial vendors that
meet your 5 year requirements.  Support is also available free via open
source, but our main objective is stabalizing a branch and then pushing
forward trunk.  At the moment we are stabalizing the 0.80 series branch
which is about complete.

Openais 0.70 is used in production in a variety of environments but I a
not at liberty to discuss the nature of these deployments.  Perhaps
others on the list could talk about their experiences with deployment.
