thanks for your interest,
i know good the normal programmation of the Pic, but for me ( is cause of my age), i don't know
good the new internet protocol and i don't have patient and time for learning new pic with
ethernet controller on board, so i look also for pic + external ready controller.
But i someone of you are specialist in this new Pic, i can pay for develop a piece of firmware (send me private post).
I think that the best way, instead of DynDNS, is a Pic that upload a little string with name file in
a ftp mode in the stardard hosting server ex www.xxxx.com
, another remote pic device or more remote pic device go to downlad the string file (parsing the string and execute the contents).
The system is not so in realtime, but i think that in this way i can use a gprs modem with dynamic ip.
