jailing transfer-only accounts

[Hans Nohack]

hello,

we need to transfer files in a secure way with different partners and
clients.
at the momet we're using commercial ssh because we found it the only way to
transfer files in a jailed environment and without offering a login shell.
we'd like to use openssh but found only some patches and wrapper scripts but
nothing "official" to do what we need.
i could image (and read on many lists) that lots of people seem to need this
feature.
will it be part of the "official" openssh some day?

thanks
hans
