The OP wants a solution that works on OSX 10.4 and Teamviewer does not.
So much modern software does not work on 10.4, though, that I considered it a lost cause and upgraded my kids' iMac rather than try to continue to support it. The OP may want to cut his/her losses and do the same.

While it might not seem difficult to purge an island of snakes, the snake's habit of dwelling high in the rainforest canopy has so far thwarted efforts to rid the island of the pest. Eradicating the snake is a priority because it triggers more than 100 power outages a year at a cost of $1-4 million and has driven at least 6 local bird species to extinction."
