Need a pGina plugin that talks and a local windows service

Need a pGina plugin that will be released opensource. It talks to a local machine windows service that utilises an existing c-library to talk to a web site. The C library is currently pthreads and sqlite-based, it is essentially corss-platform, but needs to be modified to support a signalling between a server thread and a sync thread (currently uses SIGUSR1 and SIGUSR2). The local windows service component then needs to act as an authority for the pGina plugin to query on login and provide an answer for each login request based on information in the windows service. The pGina configuration page needs to allow entry of credentials for the windows service to persist and use to remain connected to the web service via the C api.
