Yep, as Bruno states, it can be done quite easily. Just install horde4
into a separate directory, point a web root to that directory, and you're
all set.

You WILL need different databases, however. That means if a user makes a
change to their preference on the old Horde, they won't show up on the new
horde, and vice versa.  I had an issue creating a blank db with the
appropriate permissions for the web user, I had to use the following for
mysql...

create database horde4db;

create user 'horde4username'@'localhost' identified by 'passwordgoeshere';

grant select,insert,update,delete,create,drop,index,alter
on horde4db.*
to 'horde4username'@'localhost';

Once I had that for the mysql db, the first running of horde 4 db creation
of tables and schemas was successful.
