[Phpwm] Web based FTP client in PHP

[php at beachboy.co.uk]

Anyone out there, have any experience with using a Web based FTP client in 
PHP?
I want to try it out on my users, I am looking for something so simple, your 
granny could use it. 
I know FTP is simple, but it's amazing how many people fail to cope. I've had 
another person complaining that it's my fault that he can't use get it to 
work this weekend, although I think it maybe something to do with his 
firewall. 
Security is a high priority obviously.
Any thoughts?
