Remote Access to your mac via Back To My Mac (Leopard)

Ok I know there are a million ways to do this “by hand”, but if you have a .mac membership this is for free basically… automatic remote access to your machines on the internet via your .Mac account. If you look carefully under the .Mac settings for Leopard, there is a “Back To My Mac” option. This basically wraps up all of the things like dyndns, etc into one easy to use package. Its really cool! Now I just need to have two machines running Leopard. I wonder if I can hack Tiger to use this?
