Please keep in mind the difference between sync and async APIs.

You download a file over FTP. KIO is async: the application remains responsive,
you get a progress dialog. The "native VFS" is most of the time used in a 
blocking way. fopen,fwrite,fclose. Which means the application freezes until 
the FTP server sends the whole data. Not good.
A remote filesystem is NOT like the local filesystem.

Anyone who has ever had an NFS mount to a host that goes offline will certainly 
see what I'm talking about (the shell being blocked for 5 minutes after each 
command; GUI apps freezing for a very long time when trying to load/save/list 
a directory...).

"KDE is not an OS platform"? If that means KDE doesn't provide kernel 
filesystems for remote directories, I would say that's rather good.
