If you're on a LAN, you can write to a NTFS share on another computer using samba... Nothing special, just samba.

mkdir /mnt/poiint
smbmount //hostname/sharename /mnt/point -o username=username

Just run it as root and fill in the vaules for hostname (name of remote computer), sharename (name of share), and username (user to connect as). Then you should get prompted to enter username's password, and the share drive will be mounted to /mnt/point (or whatever directory you specify).
