There are probably some ways around this using Windows environment
symbols.
However, this would be so far outside of the typical Windows
programmer's
paradigm that trying to introduce it now would be tantamount to
introducing a
whole new operating environment.

Indeed, these critters have grown so accustommed to "I'll solve this
problem MY
way, regardless of whether it clashes with anything else" that the
probability
of changing it short of WMware or equiv. is indeed quite low.

Yep, and one could argue that while perhaps not to the same extent, the
same is true of UNIX environments i.e. it is not technical issues, but
rather culture issues which are the biggest impediment to App stacking.

In some ways, OpenVMS is proprietary and has a culture associated with
"this is the way you do things.." and that is a really good thing. This
applies to things like app clustering and different application modules
(written in diff languages) data and resource sharing rules that need
to
be followed in order for everyone in the sand box to play together
nicely
in a safe, scalable and very secure manner.

Now, in the UNIX environment, in order for an App to take advantage of
the
local OS platform clustering technology, it needs to follow that
platforms
rules for clustering. Technically, its not likely an issue, but doing
so
would mean that application is now much less portable than if it were
not
written to take advantage of one OS platforms clustering. And in the
UNIX
world, portability is a a much bigger deal than it is on OpenVMS. With
VMS,
if you follow the standard rules, then your app should have no issues
co-existing with other app's on the same system (assuming overall
performance
is managed of course.)

[insert discussion from those who think UNIX culture of doing their own
thing is not an impediment to App stacking on centralized UNIX
servers.]


Actually, it is very common to "app stack" under UNIX of all flavors, mostly
because that is exactly what you
are doing with all kinds of servers such as web servers, ftp servers, e-mail
servers, etc. User applications also tend to run very well, as they are not
capable of clobbering each other, memory or process wise.

Windows, if you put something like Citrix on it, has no trouble at all
running a few hundred copies of Word, Excel, Outlook, Access, InDesign,
Terminal Emulators, etc.

The culture clash you allude too seems to be dissolving in the current $$
squeeze, though Windows still lacks a decent workload manager. AIX has a
very good one, and other versions of UNIX have - "sortof" halfway attempts
at it. VMS has a very good workload manager of course.
