Installing Dropbox on Centos 6.2 owned by root. Demonstrating that the dropbox folder is owned by root with read permissions to all

"root" user gives read permissions to all users

[root@localhost Dropbox]# ls -la
total 436
drwxr--r--. 6 root root   4096 Jul 17 20:01 .
drwxr-xr-x. 3 root root   4096 Jul 11 20:11 ..
-rw-r--r--. 1 root root     29 Jul 17 20:01 .dropbox
drwxr-xr-x. 4 root root 151552 Jul 17 20:03 .dropbox.cache
drwxr-xr-x. 2 root root   4096 Jul 11 19:28 ePubs to Share
drwxr-xr-x. 4 root root   4096 Jul 11 20:14 ePubs to Share (1)
-rw-r--r--. 1 root root 269894 Jun  7  2010 Getting Started.pdf
drwxr-xr-x. 6 root root   4096 Jul 17 20:03 stagbuild
[root@localhost Dropbox]# cd ..
[root@localhost DropboxRoot]# ls -la
total 12
drwxr-xr-x.  3 root root 4096 Jul 11 20:11 .
drwx------. 48 epub epub 4096 Jul 17 20:01 ..
drwxr--r--.  6 root root 4096 Jul 17 20:01 Dropbox
[root@localhost DropboxRoot]# 

But the "epub" user cannot see/read any files in this directory:

cd DropboxRoot
[epub@localhost DropboxRoot]$ ls -la
total 12
drwxr-xr-x.  3 root root 4096 Jul 11 20:11 .
drwx------. 48 epub epub 4096 Jul 17 20:01 ..
drwxr--r--.  6 root root 4096 Jul 17 20:01 Dropbox
[epub@localhost DropboxRoot]$ ls -la Dropbox/
ls: cannot access Dropbox/stagbuild: Permission denied
ls: cannot access Dropbox/Getting Started.pdf: Permission denied

[epub@localhost DropboxRoot]$ 

Any ideas?

For a directory, read permission isn't enough. You also need execute permission in order to enter the directory.
