Ye, but it requires the user struct to be passed as a parameter, which 
this plugin doesn't even use.

Also, it seems the ip address is stored in a different format than used 
by the old getenv("IP") (which was a string)

I need to return both the IP and the email address as a string to drop 
it into the old code.

I attempted to use the drac plugin as a base (the new 2.0 compatible 
one) but i found the code hard to follow, and also DRAC seems to just 
use the IP, while whoson also uses the email address.
