Last night was the SharePoint UK User Group meeting, and they had a number of vendors in to discuss their wares.
One that I’d not seen before, and set my toes tingling was about Geo-replication in MOSS, by Syntergy. They talked about a number of their products (and their Sharelink product – for integrating SharePoint and Livelink – was interesting), but the main part of the demo was Geo-replication. Basically, you can select (at a broad or narrow level) what you want to replicate, where you want to replicate to, what events you want to replicate, and it does so – including scheduling, and dealing with collisions of changes and resolving them.
