SSH v2 protocol supports banners. man sshd_config look for 'Banner'

This will however display to everyone standard ssh shell logins and sftp alike. There is no sftp only banner feature. And doing what you suggest will cause sftp not to work at all.

There are a few chroot projects for OpenSSH. You may want to consider the chroot sftp-server patch(it is out on sourgeforge) since it would be less work to setup/maintain.

I'm sure SSH Corp has something like it, but I have not looked at their product in years.

No. sftp is a 'subsystem'. So restricting it that way is not possible since sshd has no clue it is a subsystem, shell, X11 forward, etc until after the user has pass authentication.
