Admittedly not a powerful reason at all. :-) Go back to the drawing board on that one ... higher developer productivity is a big deal!! ;-) > 2) The ability to swap in and out different clients, and leave the server > alone.

XML + HTTP doesn't change that interop picture. However, I think it's true that since XML is text, most any programming tool nowadays can work with it at least a little bit, and that's not true of any normal RPC. One doesn't do bit-twiddling in VB, it's nasty for most protocols ... one needs expensive (and usually proprietary) tools to create DLLs to do the bit-twiddly stuff for you. The cross-platform interop story is one reason I never could support the RMI story ... there was none, and interoperability between systems is the driving force behind every networked application. - Dave xml-dev: A list for W3C XML Developers.
