Trying to create an scp chroot jail

I've got a vendor/parner that has requested an scp connection to push files to us. We usually go with sftp but this partner isn't interested in wrapping sftp in an expect script just to push out some files. It seems like there is a wasteland of info out there on how to accomplish this.  In my search I;ve stumbled across two options.. rssh and scponly.  I've read more bad than good about scponly so I'm not going there. The other option rssh comes more recommended but it's a pain to configure with the support libraries.

So.. is there another method to chroot jail an scp user?
