Since SFTP is defined by the IETF SECSH Working Group (although I see 
the last SFTP draft has expired and isn't listed on the web page[1] any 
more) I would imagine that OpenSSH will always have them.

sftp and sftp-server are still being developed (see the CVS logs) and 
there are other things that haven't been completed yet (eg Ben's sftp 
readline patch).  If there is something you want that it doesn't have, 
add it and send a patch!

PuTTY, SecureCRT and's Windows client all have sftp clients.  I 
stongly suspect there are others.

There's an old SFTP draft here:

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
