There are really issues with kiofuse. Tried to transfer a relatively big file,
got me 6 mbit/s and intensive CPU load, with plain sftp I got 100 mbit/s. I saw
in the log

log_kio_sftp: seek, offset =  31170560
log_kio_sftp: write, offset =  0 , bytes =  4096

So kio_sftp is called just to write 4K, because "cp" does it. KIO provides
file_copy, file_move etc for these operations. FTP has shortcomings as well,
because no seek is possible kiofuse is not able to mount the ftp kioslave. 
I am quite sure an analysis will discover other shortcomings as well. I must
say I am not really fan of inventing the wheel again here, maybe using existing
fuse technology like sshfs is a better choice, or gvfs.
