We'd like to simplify our deployment. Now our admins have to install Webware
multiple times for each appserver instance on multiple servers. It would be
easier to just deploy once and have all instance refer to that one check
out.
We also see better performance running with a pool of single threaded
appservers instead of using the ThreadedAppServer. So we are looking to
substantially increase the number of AppServers running and don't want to
setup dozens of Webware directories that only differ in port number and some
logging parameters.

We're only using the HTTP adapter for our current tests and it didn't seem
to care if that file exists. So I didn't look any further...

Thanks I didn't see that config. We'll just specify it also on the command
line and now I won't have to override addSocketHandler() anymore
