Thinking about the future of EPICS,
some items on my wish list are:
[1] A tracing mechanism in to find
out which host/user last modified this PV.
Yes, that will take additional memory.
When trying to locate some aberrant client,
this is most valuable.  Also, useful when
trying to identify which user thought
we had a new d-spacing in our monochromator
(for example).
[2] An EPICS "ping" command or something that
a sysAdmin could use to identify all the EPICS
IOCs within a subnet.  Maybe there is already
documentation on how to do this by probing
a certain port or some other elegant method.
[3] Building upon [2] above, a client request
for a list of all the PVs offered by a
chosen EPICS IOC.  This would be a list
just like the "dbl" command from the IOC shell.
Why is this useful?  It could be used to answer
the question "Where is this PV?" (Maybe this, too,
is already available from the low level C calls.
Maybe I should take the EPICS course.)
This short set of tools will aid the sysAdmin
in taming the set of EPICS servers now that anyone
with a Win PC or Linux can add an IOC to the subnet.
