Some more good thoughts on this are from Rands. He makes a strong argument that a lot of the tools we think we need for remote workers can in fact be a hindrance - the delays in video/phone chat in meetings can be killer, as I've found on both sides.
For myself, I've found that being on the remote end it's usually easier to not interject, which in turn becomes a problem, since my feedback isn't getting registered at the time it's most relevant.
