Hi,
I wish that the ftp chrootkit made by Stephen Noble is integrated in the newest version of SME

In my humble opinion the standard settings of proftpd are not save because every user can "climb up" to you primary html dir! With this package you can solve that issue and I think that option should be in SME out-of-the-box.
For a test...
