I searched around for this and found some requests but no actual hacks.
I have a members only area on my site that uses a cgi script to handle sign-up, login, password retrieval, members manage and emailing the members.
All those functions are already a part of VB and are handled much better the any password protection script I can find. Would be really nice to merge the two somehow. Then members could have access to both the members only section and the forums using just the one password/login from VB. And best of all, I can use the CP for members management and emailing.
I'd pay for a hack like this, as long as it's not too expensive
