When I worked for Sun Microsystems, I was able to work from home. There was an office within 50 km, but my manager and the rest of my team were 2-5000 km away. Now I do IT work for a university and I have to drive in. (No public transportation in my neighborhood.) I'm trying to work my way up to biking in, since it's only about 11km, but this is a very hilly region, and I'm out of shape.
Some employers seem to be fine with remote employees. Others don't seem to quite grasp the idea yet.
