   That depends on what you consider "prohibitive".   
      
   The way Markus suggested it, the shirt is meant to entice sysop to make an   
   effort to upgrade to IPv6. I am afraid that "you pay EUR 20 and then when you   
   pass the IPv6 test, you get the T-shirt", isn't all that effective in   
   recuiting new members for the Fidonet IPv6 club...

   I get your point. But you already have IPv6. So there is no need to try to   
   seduce you with a certificate... ;-)
