ftpchroot root directories

[David Newman]

Greetings. I'm setting up ftp access* for a number of users to a 
directory structure like this (assume "/" is an alias for the top of the 
tree):

Username directory perms
------------------------
user1    /          rw
user2    /projects  r
user3    /projects  rw
user4    /          r
The FAQ and the ftpd(8) manpage say that chrooting goes to a user's home 
directory, and nothing about permissions.

Is there some other way of setting this up?

thanks

ps. FTP is the client's choice, not mine. Same with this directory 
structure.
