>>While RIA is pretty awesome, it has a few glaring potential points of failure. One of them is the synchronization between the two projects (server and local/browser.) Although .NET tries to keep those two synchronized during development, sometimes the paths separate and then it can be quite difficult to manually re-synch them. Some frameworks (such as IdeaBlade, which is what I use) simply create a "shortcut" to one project instead of trying to move two projects along in lock-step. In other words, the design is normalized, changes happen only in one place.

Sorry for the delay in getting back to you.
My understanding is that Ideablade creates a "link file" or a shortcut for a given class object from the Silverlight side to the web side through the Ideablade template that is generally used in Ideablade applications. When the project compiles, Ideablade directs the compiler to the same physical file, which resides on the web side of the project, thus making sure that both Silverlight and Web sides compile exactly the same code. RIA, on the other hand, creates a proxy on the SL side, which has its own code that is used when compiling the SL side of the project. Since this proxy file is physically different from the web side file, these two files can get out of synch at which point the project can spin out of control.
If you are further interested in this (and actually hearing it straight from the "horse's mouth", I suggest watching this video (this particular explanation starts around minute 3):
