Technically, the correct place for per-user, per-machine settings like
SpamBayes databases is (in Windows 2000 and newer):
c:\documents and settings\username\local settings\application
This keeps the databases as part of the individual user's profile, but
it stays on the local machine and doesn't roam with the rest of the
profile to the network.

This isn't completely necessary. If SpamBayes isn't installed on a
machine, any files in these directories will simple be ignored - no
error messages or anything. Of course, spam will not be filtered, but
nothing really bad will happen.

Yes. The directory:
c:\documents and settings\username\local settings\application data\
Will already be in every profile, but you'll have to create a SpamBayes
subdirectory. This can be easily automated by adding this command to
your login scripts (all on one line):
IF NOT EXIST mkdir "%USERPROFILE%\Local Settings\Application Data\
SpamBayes" mkdir "%USERPROFILE%\Local Settings\Application

You could copy small "default" databases to their profiles using a
similar commands to those I'm showing above.

This is why using a default database might be a bad idea.

I've tried this, and performance is not bad on my network. I've used the
user's home directory, defined by the %HOMESHARE%\%HOMEPATH% environment
variable. You can automate the INI file-path settings with login
scripts, or with Windows Installer packaging.
