Hi:

It comes to my mind that the interface for channel access V4 should be also discussed and defined by those people writing the high level (machine)physics applications. They will probably have the highest demand for new features.
I completely agree with a high level approach.
I'm spending many evenings and weekends in the control room
these days and my most important tool is Matlab w/ channel access.
In there, it helps to have an API ala
    cavity_amp = caget('DTL_LLRF03:cav_amp')
and then cavity_amp is a double[1024] or int[16k],
far removed from the low-level API of assembling
a property catalog, connecting, ...

Will Kay and Doug coordinate this issue? Otherwise I'll be glad to help.
I did some LDAP-based tests for a directory server which is on the wiki,
I'm also checking ZeroC Ice as suggested by Andy Foster for performance
and ideas as a possible communication mechanism.
Overall, however, I clearly don't have the time that I'd like to have for V4 work,
so I'd not only be a bad coordinator but actually wonder if
I should quit before the rest of the group counts on my work
and then we all fail because I can't deliver.

Thanks,
-Kay
