Alternative for visio server-side automation

Mircosoft recommends against server-side automation of office tools (Considerations for server-side Automation of Office)
However, I see no other options. What I’m trying to do, is convert vsd files to html (image+map for hyperlinks). This is not yet possible in Aspose.Diagram, which was quoted in answers to similar questions here. LibVisio which is/will be used in LibreOffice 3.5 is not finished and also doesn’t support hyperlinks.
