Note, this is not the same session, it's a different connect with the same 
user credentials. I don't see a problem with this. It's not a security 
problem and it's hardly a load problem. Users usually don't have more than 
one IP at their disposal at the same time. This is one of the few cases where 
this is different.

AFAIK, there is no option to allow only x logins per user, only x logins per 
IP. You could go to the vsftpd mailing list (if there is one) and ask about 
this additional feature.
