Looks like there are several people either running or getting ready to run the PHP version already. The only thing left for the front end scripts is porting over the file attachment code.
So, if you find any bugs in the front end scripts go ahead and post them here. Once I get a complete port done then I'll be setting up another forum category for the PHP version that will contain forums for hacks, installing questions etc.
Should begin porting the admin scripts this week.
