We do a skype meeting once per week, for 1 hour or two. The day of the meeting I had to stay at work until 8-9 pm, so this day I come to work late in the morning.

Email+issue tracker for the rest of the communication. Asynchronous communication help me to stay focused.

It works really well for both of us.

When I worked remote for a shop out of London (I'm in St. Louis, Missouri, so the time difference is similar), I just woke up a bit earlier. It worked fine. I was there early enough to catch what needed to be done so they didn't need to stay longer just to accomodate me.
