"No SOAP for you" I have the recipe now. I can prepare for myself. I like those Seinfield episodes. Anyway, by adding SOAP does not give anything immediately, but indirectly it opens up the door for writing applications which work seamless across firewalls, since it will be based on HTTP port 80. Which will be open all the times. I think, Mozilla supports SOAP, as I read in the book hosted at http://books.mozdev.org BTW, why one cannot write fully functional web-interface for RioCar? Whats stopping it?
