[Coco] IP packets on my coco

[Dave Philipsen]

The ESP8266 itself.  In a full-blown networking implementation you would 
be able to have multiple connections all going at the same time.  This 
would be difficult with the ESP8266 as it stands now. The fact of the 
matter is, if you use the ESP8266 for a DECB program it will be more 
than adequate as you won't be doing any multi-tasking where other 
programs would need to access it at the same time.  If you wanted to use 
it under NitrOS9 which could also require that you write a device driver 
for it, then you may have a problem running multiple programs 
simultaneously that would be using the internet.

As I said, though, it's possible that someone could re-write the 
firmware of the ESP8266 to make it work.  There are already people out 
there who are customizing it.
