An FTP alternative ?

[Leo Lapousterle]

Hello :)

I'm fed up with FTP servers : FTP is great, but I need some admin stuff
like privileges (one user can upload but not download, for example)
unavailable for FTP... at least for those I've tested.

Is there an alternative way for FTP, allowing individual privileges?
I found hxd (hotline protocol, I used it 7 years ago!), it's very powerful
but quite discontinued...

Anybody has another idea? :)
Thanks!
