Hello, buddies!
Let me introduce my blog
http://x-dynamics.blogspot.com, in which I would cover technical aspects about NAV integration. Nowadays there are several articles about implementing web-server for classic NAV, interaction with web-server from NAV client, posting emails and other tricks.
RTC is not covered yet, as I'm novice to it.
You could check them and send remarks. Thank you, you are wellcome! :!:
