We are looking into a custom document route, and I know about the ICustomRouter interface. Can it be used in CSOM?
The ICustomeRouter example here: http://msdn.microsoft.com/en-us/library/microsoft.office.recordsmanagement.recordsrepository.icustomrouter.aspx
references: using Microsoft.SharePoint;
...which leans towards the Server Side Object model.
I don't see anything for "routing" or "records" here for the 2013 API: http://msdn.microsoft.com/en-us/library/office/dn268594(v=office.15).aspx
