The CoCo does have a web server of sorts, and in some ways its more
"native" than the C64 and Apple 2 web servers that exist, although in
other ways much less.

More native because its written in Basic09 and runs under OS9, an
operating system and language that shipped on the original CoCos
(afaik the other 8 bitters are using ports of contiki or custom,
dedicated software).  This means you can continue to use your coco as
a regular coco while it runs the web server as a normal OS9 process
and development of other networking programs can be done in the same
languages anything else written for our CoCo is written in.

Less native because we don't have a native tcpip stack at all, instead
the CoCo implements the application layer (processes HTTP, and can
provide dynamic content fwiw) but does not implement IP or native
networking hardware.  Instead, it uses a hybrid solution that provides
IP services over the bitbanger serial port and a host PC to do the IP
side of things.  The project did win the "Retro Computing Challenge"
last year (or maybe it was the year before.. time flies), and the
httpd server is designed to work with a native networking solution,
should the hardware ever be created... but still it isn't currently
completely satisfying.
