I searched for a hack that could do what I need, but could not find any... if there is already something similar available, please let me know.

I need the following two features:

1. The system would register the IP of users not only when they post messages (as vB does today), but also everytime they login in their accounts (even when they do not post in that session). This data could be persisted for a month or so, and the hack would allow to check if and what other users had the same IPs... (similar to the current vb admin feature, but with all registered IPs - from posts and logins)

2. The system would avoid two different user accounts being used (logins) from the same IP in 24 ou 48 hours (except for administrators...).

There are some users faking different id's in my forums to deceive other members. This hack would help preventing this kind of problem.
