Worldwide internet connection

I'm planning to go on a trip around the world, and I'd like to share Pictures and Video with my family and friends back home, so I'll need an Internet Connection.
I have a laptop computer, and, since i'm planning to go in not very high-tech countries, I'd rather not have to depend on Internet points, wich may be very rare.
Is there an international telecommunications provider that offers the service of a worldwide connection (eg. via satellite phone, or portable dish)?
Possibly a flat-rate subscription, so that I won't have to worry about time of connection or amount of data exchanged?

It may seem a crazy question, but I simply had to ask :-)

Thank you everyone.

I remember reading exciting reports 6 or 7 years ago about worldwide satellite coverage and Internet access that was just around the corner. It seems that corner has not yet been reached. There is worldwide (or close it) coverage, but not from a single carrier. Some claim worldwide, but when you look at their coverage maps, you see it is not so.

Here's some stuff to read.
HoboTraveler.Com - Worldwide Internet Access
BusinessCom Satellite
Satellite Signals
DMOZ Provider Listing

Perhaps other readers have personal experience with these or other services.

I'd be curious what you decide to do - keep us posted.

Thanks Digerati, I'll take a look at those links :-)

I'm curious to see if someone else has any other info lol

Although I no longer do any worldwide traveling, I too am curious to see what those that do travel have to say.
