General question: passing variables between plugin and sections
While coding I noticed that superglobals like $_SESSION are not acting as superglobals in Textpattern. If I assign a value to a $_SESSION array, that array value is available within the section you embed the plug-in tag in, but not in other sections.
If you put
<txp:pgp>session_start(); global $_SESSION</txp:php>
at the top of each template, the $_SESSION is available in all sections.
There must be a (security) reason why superglobals act as they do in textpattern, so what is the best method to pass variables between a plugin and a section and in between sections? I cannot find any documentation about this subject.

No plugin authors who ever had to work with the same issue? I find that hard to believe…

I think this is a result of eval() the plugin code. So you have to declare your global variables explititly.
See Ruuds answer for similar problem here: http://forum.textpattern.com/viewtopic.php?id=31364.
