Todd,

Can you elaborate on this?  I'm somewhat confused because when I do a packet 
trace of what is happening during an sftp transfer I see SSL connection 
establishment followed by data transfer.

Also, I don't know of a case where sftp is not available.  I've used it on 
most UNIX flavors and Windows.  Where is it unavailable?

TIA,
