It's nice to see that such complex applications are possible, though
PmCalendar seems to work quite differently to what I've in mind.

I prefer pmwiki markup as well.

Very cool, indeed.  AFAICS, your simple code could be the basis for an
extension allowing one to include dynamic content in the way that I

For the second solution that I illustrated in my original posting, the
markup could look something like this:

(: remoteout http://some.dom.ain/cgi-bin/some-script?foo=$inp_x&bar=$inp_y :)

Here "http://some.dom.ain/cgi-bin/some-script" is a CGI program that
outputs wiki code.  The expressions $inp_x and $inp_y are replaced by
the values of the corresponding GET parameters found in the URL of the
current wiki page.

For embedding CGI generated images into wiki pages, the following markup
could be used:

(: assemble http://some.dom.ain/cgi-bin/some-image-creator?foo=$inp_x&bar=$inp_y :)

"assemble" simply assembles a string using the GET parameters.  The
string is then interpreted by pmwiki.  In the above example, it's the
URL of a dynamically generated image.
