Is it possible to create a list in WSS 3.0 based on a custom template using SharePoint web services?

I want to create a SharePoint list using SharePoint web services (instance is SharePoint Services v3.0). That list should be built from the custom list template that I have created previously. Browsing through MSDN documentation resulted in the following resolutions:

services.ListsService.AddList(title, description, templateID);

or

services.ListsService.AddListFromFeature(title, description, featureGUID, templateID);

Now, if we take a look at the first implementation, there is a problem as the templateID do开发者_如何学Pythonesn't exist for my custom template - it refers to the default ones instead.

The second implementation is no good either as I need the templateID again, but I also need the feature GUID which I have no idea how to get. Could anyone help please? Thanks.

It has been confirmed to me from people from Microsoft that, unfortunately, it is not possible to utilize features to create a SharePoint list using SharePoint web services. It can be either done by developing custom web service, or by using Object Model.
