Hi,
Regarding WordPress, the script is very far removed from when it was integrated with WordPress, so a new effort would have to be undertaken to do the integration.
As for supporting the code, the situation is still the same in that there are no plans for further support or development at this time. However, there is nothing closed source or proprietary about it — you can seek help from anyone who is generally familiar with PHP and/or MySQL.
Sorry that I cannot be of much help at this time, but good luck! Feel free to use this forum to share further development.
