Please download release 3.1.6 I have added the UrlOptions property to the SitecoreFieldAttribute class. You should be able for force the server path like so:
[SitecoreField(UrlOptions=SitecoreInfoUrlOptions.AlwaysIncludeServerUrl)]
public virtual Link MyLink{get;set;}
You can also added other options by piping the flags:
[SitecoreField(UrlOptions=SitecoreInfoUrlOptions.AlwaysIncludeServerUrl|SitecoreInfoUrlOptions.LanguageEmbeddingNever)]
public virtual Link MyLink{get;set;}
