If you can ping, you might want to try VNC next--it is simpler to get going
than Netmeeting is--if you can do a simple unencrypted VNC, you know that
you've got the basics covered--you have the right address, and there's no
NAT or firewall getting in the way. Then you should decide whether to
pursue NetMeeting --which you can configure on her end via the VNC
connection--or just add encryption to VNC and use that.
