What I mean is with respect to the three tiers of service you can buy.
The Plus tier, which comes with one google account you can add to your InSync client.
The Pro tier, which comes with three google accounts you can add to your InSync client.
The Business tier, which is reduced (from the Pro tier) to just one google account that you can add to your InSync client.
The reason I ask is that some of our users (and we are all on Business edition) inquired about connecting both their Work and Personal google accounts on the client, because Dropbox (which they currently use) allows them to have both Work and Personal dropbox connected to the same client.
