I am not certain if this is what i am looking for.
As mentioned, the two workstations to be connected are not in the same
network. Also, i don't have a spare machine to install an IIS and a
WebDav on. Isn't it possible to have Outlook store all of it's
information concerning the specific calendar in a file (which is
saved on the FTP, in the way written in the first post?)

No. Access to a PST is active and two-way. FTP protocols simply don't
allow that type of access. However, nothing prevents you from closing
Outlook and FTPing the PST to a server so that others can download it and
use it at their location.
