We do not have an LDD component representing a BizTalk; however, using the SDM SDK (see http://msdn.microsoft.com/vstudio/teamsystem/architect/sdm/default.aspx) you can create such a component. (so you'll have to provide the HostingDefinition for WebService and ContainmentDefinition for HttpServer in the model for your BizTalk LDD component)
