Network, file shearing, on AmigaOS is hopeless or is it?

So other platforms have DropBox and Google Drive, Samba / Mirosoft network, NFS, and so on.
We have where old version of Samba, and we are having problems whit ever dated Socket API, it put a lot of restrictions on what we can port over to AmigaOS, I think it's time we work around this problems.
We need our own file sharing system, I think this the only way we can control compatibility whit other systems we use.

We are stuck whit FTP based file shearing, and it's not horrible simple to manage.

The conclusion is that we need our own Windows/Linux/AmigaOS Client/Server software.
I have thinking the simplest form of file shearing might be some kind of file sync system.
