Aren't we now in a discussion about the definition/distinction of the IB
engine and the "server application" layer. Where does one stop and the
other start?

Bill Karwin, is correct when he suggests that the IB engine should be
focused on core functionality.

There is, however, a very strong and valid point for suggesting that new
functionality should be provided.

Doug, your suggestion about a "server companion" implies that it's an
add-on. I personally see it as more "core" to the product (a wrapper
around the engine). I would have no issue with different "flavours" of
wrappers - the current lightweight and the "new" heavy-duty
super/scheduler/batch/batch data import/export processing.

Yuck! I agree with Bill Karwin. This stuff should not be part of the
server
at all.

What about defining an architecture which provides for server companion
processes? These would run on the server alongside the main server
process(es) and would be responsible for script executions or other
stuff
which should run on the server machine?

Perhaps ISQL could be expanded to direct certain tasks to a companion
process via a pre-process dispatcher. I don't know how the server
directs
incoming requests but it seems that early in the process it would be
feasible to direct a certain type of ISQL operation/command to another
running process and use the TCP/IP connection as a pass through
mechanism.
This way the main server stays lean and mean, as it should be.
