I've known about Groove since it was first delivered by my former Lotus and Iris colleagues. This was my first opportunity to use Groove in a heavily collaborative environment. Three companies, two in Canada, and one in the US. Sharing documents really shouldn't this difficult. On a different account, we're using SharePoint, but it requires VPN access. So, Microsoft offers a dozen ways to share files, but none are interoperable. It's no wonder that people are looking to Google for simple solutions.
