There's plenty of us wanting to install our BIM server on a Linux machine. It's an obvious need, since most of the servers run Linux, and having to install/maintain another server just for BIM does make no sense for a company.
@Graphisoft : it seems you don't plan to deploy BIM Server on Linux. But there's an alternative and simpler solution : support it through Wine.
Unfortunately, it does not work with the current version. But you could consider hiring someone from the Wine Project to make it work.
Since BIM Server is not a complex program with a lot of fancy and modern features, it should be possible with a very reasonable budget, far from developing a full Linux release.
