publicfile and htaccess restricting or some other authorisation

Hello,

I want to setup a secure http server so I want to use publicfile.
It will became a real simple setup

Multiple hostnames to some directory's each contaning only some normal
files. So the viewer will only see the directory listing.

Site1.example.org to /home/site1/
Site2.example.org to /home/site2/
Site3.example.org to /home/site3/

No, html layout nothing fancy

I want to have some username protection on each site so only the user of
site1 can view site1 and site2 only site2.

This is possible with a massive apache with htaccess implementation, but
is it also possible with publicfile.
I love the small size of publicfile and the speed of answering.
