I use gotomypc myself, and it works great. But can't Remote Deskop be used through firewalls using a VPN? And does that have the same weaknesses as #1?

If you're good at networking and the client software supports it you can use non-standard ports and port map within the firewall/router which will greatly slow down crackers. If you open standard ports your Remote Desktop security is no better than with no firewall at all (but the firewall prevents other attacks on other ports).
