Does it make sense to use RIA Services as a service provider to an ASP.NET web application as opposed to just a Silverlight application? We have an infrastructure constraint that the services and the consumer are on different physical machines thus need to cross a service boundary. We have not seen any examples of using ASP.NET as a consumer of RIA Services.
Yes you can here is a post that walks through using WCF RIA Services in a regular ASP.net Web Application.
