No, it's actually possible in lots of different ways--sometimes it just
takes a day or two for an answer to show up (especially since this is
popular vacation time for many in the northern hemisphere).

Yes, you can set a variable that would be used in another page.  Try
something like this:

  <?php
    $DoubleBrackets['/\\[:setmyvar (.*?):\\]/e'] =
      "substr(\$myvar='$1',0,0)";
    $DoubleBrackets['/\\{\\$myvar\\}/e'] = "\$myvar";
  ?>

The first statement enables markup of the form [:setmyvar <value>:], which
sets $MyVar to be <value>.  (The substr call is just a way of replacing
the directive with an empty string.)  The second statement enables 
markup of the form {$myvar}, which is replaced with the current value
of $myvar.

Thus you can put 

   [:setmyvar some text here:]
   [[include SomeOtherPage]]

and inside of SomeOtherPage the markup {$myvar} will be replaced
with "some text here".
