Accessing 4D data file residing on a remote volume

To all

I have a client who has used a custom 4D 2003 client-server database running
on Windows to collect clinical data over the past 10 years.  They have now
migrated to a major hospital information system.  However they want to
archive the 10 years of clinical data and wish to access it in the 4D
database after it is archived.

Constraints are:
€ Transferring the data to the new system is not an option
€ They want a single-user configuration
€ The program file and 4D need to reside on a local client running Win XP
SP2 or possibly Win2K SP4
€ For security purposes the data file (780 MB) needs to reside on a remote
secure shared volume
€ The hardware for the shared volume is an EMC NAS storage server, the file
system is NTFS, and the OS is (possibly) Win 2003 server (EMC is the
manufacturer, and NAS stands for Network Attached Storage)
€ The network connection/protocols between the client workstation and the
shared volume are TCP/IP over WAN
€ The shared volume will be secured through user/group access set by
permissions; if there is any need to write to the data file this can be done
if the user has modify permission

Given this configuration, would there be any problem in the single-user
client running the 4D clinical application to access the 4D clinical data
file residing on the shared volume.  In my mind I would not think so, but
wanted to check on this list with people with more experience in sunch a
configuration.
