One thing I'd particularly like when dealing with my parents' issues is an _easy_ way to set up remote screenshare and access. It's one thing when the problem is that their computer isn't booting (in which this site would definitely help ;)), but another if the problem is that they can't find a file they downloaded or something like that.

I'd pay for a tool like this that was easy to set up and use that didn't have to involve my parents installing TeamViewer, coordinating a channel, and so on.

Edit: Thanks for the advice all, will install one of these suggestions when I head home for the holidays.
