I've come to the conclusion that as I have neither the time nor inclination to spend my spare time working on Maypole, and I haven't used it for any paid work for several years, I won't be investing any more time on actively working on it.
However, I could be persuaded to work on it for a decent fee, and I would be happy to apply any patches applied and release new versions with fixes.
I'd also be happy to hand over the reins to anybody who wants to take over.
I do have a lot of ideas in this area, but family and work commitments mean that I'll more likely experiment on top of the newer frameworks that exist than try and rework Maypole beyond recognition.
I still think there is a large hole in the "market" for a more high-level app server than Catalyst, etc providing something more like Drupal in perl but I'm not entirely sure how to do it.
I guess I'll just see what happens, in the meantime I have plenty of other open source code I'm interested in and hacking on - from Autodia to Padre and Plack.
