As far as I can tell there's very little _at all_ in the mailing
list archive since August ...

I do. I think it's extremely useful to have a file transfer protocol
within the framework of SSH, because most security-conscious people
accessing a remote account will already have set up SSH
authentication credentials.

Moreover, SFTP is a qualitative improvement over SCP, partly because
it's more general and can usefully be used for complex automated
tasks, partly because it's actually vaguely _possible_ to secure a
client against a malicious server (SCP has a wildcard issue that
makes this highly inconvenient), and largely because the range of
clients you can plausibly write is so much greater. PuTTY's SCP
client now uses SFTP as the underlying protocol whenever it can,
falling back to the old unreliable SCP only when it has no choice.

I might be the only one, however; nobody has shown much interest in
answering my clarifying questions or in the extension I proposed (to
allow user details to be looked up, so a client could understand
`~fred' and also so that the uid->username mapping in the
recommended form of the long listing could be done in other contexts
as well).

Cheers,
Simon
