Will Pen do the trick?

Hello
I am looking arround to build a multihomed hosting service.
I came across Pen wich looks quite nice but i want to be shure about a
few things.

-Is it possible to forward POP3 connections to another host when others
are down or refusing connection ( all hosts in the pool are backup MX'es
  of eachother)?
-When Pen is used for FTP will the uploaded data also be placed on the
several hosts in the pool or is extra sync required?

We are planning to use Pen on Freebsd.

Kind regards,
Raf Goetschalckx
