Does anyone have any experience with any trip tracking websites?

I'm planning a couple week trip and would like my family and friends to be able to track my progress. I was hoping to use Google Latitude (allows others to see where you're at using compatible cell phones' GPS function) but my phone doesn't support it. I'd like you be able to log on using my cell's internet and update my location and occasionally stop in at a public computer and email / upload photos.

 

Whatever happened to simply riding a motorcycle and forgetting what you left behind?....that said,buy a LoJack if you want to be tracked...:>)

 

Internet, cell phones, GPS and thongs. And LoJack. Oh come on. It's not like I'm draggin' the mother-in-law with me in the side car, just trying to keep others from worrying too much.

So...no one?
