I work in a small office of a big company and have a 10 hour timezone difference to my most important co-workers. We chat on the phone but I don't really enjoy it. I'm not sure video chat would help, but I might be willing to try.
But it would be slightly inconvenient because of the timezones. We might have 10-20 people from 5-10 locations around the world. This means that many participants call in from home before work in the morning or after work at night.
That said, I'm quite happy working remotely mostly from home.
I feel that travelling occasionally and meeting the people in person (and having lunch, dinner, beers together) makes it much easier to work together. There's no substitute for human contact.
We have a Hangout open all day in the office, displayed on a 60" TV. Anyone that's working remote can jump in whenever and it's somewhat like they're in the office. Audio is my only complaint. Sometimes it is difficult to be heard

Do you know what the Google monthly fees are? Is the bandwidth consumed a concern?
I've heard a couple other stories like ours. One I remember specifically was a company with a 50/50 mix, they did ALL meetings from their own desks on a hangout so that everyone had the same presence, the remote people didn't feel left out, because everyone has to fight for the same one audio track.
As for bandwidth, it hasn't been anything that we've been troubled by. Been using it for nearly 2 years now. The client on the remote machines has some hiccups from time to time and is somewhat of a resource hog. But if you keep it in the background it isn't too bad.
Our time zone difference isn't as extreme as a 10 hour difference. We have offices -1 and +1 from our current time zone so it makes it easier.
A talk I attended earlier this year had a similar setup to yours and what they did was record all meetings and had a culture of always doing the meeting regardless of wether people could join. Then if you missed the time you chimed in later after you watched the video. Decisions were handled in a similar async fashion.
There are plenty of easy browser-based video chat applications using WebRTC like https://appear.in/. You can send people URLs to your video room and there's no software to install.
