Does anyone know if the next version of Mere Mortals will include more tutorials and guidelines on the creation of web services?

The current MM developer guide describes the basics, but there are some issues that are not covered, such as implementing "secure" web services, and best practices for architecting, integrating and communicating with web services using Mere Mortals business objects.

Here an example scenario: suppose I have a web form that currently uses a business object, "boSomeBizObj", to get and save a dataset. The user modifies some of the data, posts back, binds back the data, and calls "boSomeBizObj.SaveDataSet()" to update the data. If I now want to modify the architecture so that I can expose that same functionality as a web service, what would be a good way to engineer this? Would I perhaps have a web service that takes the data (indluding mofications, somehow) as XML, translates it into a DataSet, then instantiates "boSomeBizObj" and passes the dataset to a call to SaveDataSet()?

Any opinions? Has anyone begun to implement this kind of functionality as a Web Service?
