[CentOS] openl2tp.org compared to openvpn

Everyone,

I am needing to set up a secure channel with another office in order to
pass some dicom files back and forth.  The remote office is microsoft
shop.  I have initially looked at openvpn, but the microsoft shop has
requested that we use openl2tp in that they already have this running.

Since openl2tp is not part of the centos repositories, does anyone have
good or bad experiences with this.

Thanks
