Yup. I place no restrictions at all. It doesn't even have to be a single
table -- it can be the result of a multi-table join, as long as all of
the columns have different names. They can be renamed using "AS", like
"SELECT,, AS hname FROM table1 a, table2 h" for
example, which would then be accessed as ${id}, ${name}, ${hname}. Take
a quick glance at the sample configuration
from the mod_sqltemplate site.

It can be from anything that can send Apache a signal (USR1 causes a
graceful restart) as well. Running apache2ctl can be done from anything
that has the right permissions to signal Apache.

As an incidental note, I'm planning on writing a PHP patch that allows
you to force Apache to do a graceful restart, but I haven't had the time
to think about the best way to do this yet.

That's correct.

You can leave your existing configuration files and create a completely
new one that handles all of your new virtualhosts.
