I believe plugins also store serialised arrays
when they store options, it makes it easy and generic to dump an array
and get it back in one piece. Plus you can never guarantee what and
how a plugin is storing data so always best to er on the side of

I didn't quite understand what the original question was asking.
Multiple WP sites can easily be run on the same server. You just need
to set them up as separate vhosts/sites under your webserver, create a
new directory for the WP files and user data and make a new database.

If you've installed apache et al via apt-get you'll probably need to
alter your apache config (/etc/apache2 ) to enable vhosts and point
them to the correct directory.
