I'm using W2k. Runs neat. SQL Server 2000, I used I-Net's drivers and
everything worked
fast and smooth. However I haven't used it intensly.

As with any W2k, use the lastest SP and hotfixes. The maximun number of
_true_ threads W2k manages
is 250 (1 uP, 1 GB RAM); about 75 are used by services, and if you'll have
IIS there, you can't have more than
75-100 threads running without severe problems. Of course, If you'd ever
have 100 concurrent users on a single orion, you'd be using a cluster(won't
ya?).

For W2k, Sun's latest is the fastest. Have proof (and an NDA, so I can't
reveal it). You can test, the results are almost humanly measurable. It's
amazing how much Sun's VM has changed since 1.2.2.

There are some utilities that allow you to run orion(or any java app) as a
service. Search the list archives.

I think the elephantwalker covered that. You can implement your own
UserManager; if you're thinking of auth against the PDC, yes, it can be
done. You'd have to write your own UserManager, and then use JNI or
J-Integra to call upon ADSI objects.

There were fixed bugs. Also, dropped connections on long-execution pages do
not kill the webserver thread, so there may be DOS vulnerabilities. even so,
it's a whole lot better than IIS. And bugs don't have the same amount of
press.
