Monetisation thru secure invites

Hi

I am looking to cross

http://buddypress.org/community/groups/wordpress-mu-secure-invites/

with

https://premium.wpmudev.org/project/wordpress-mu-affiliate

Can invite only option be added to the affiliate plugin.

I have thought about using the signup code plugin but it seems to be a bit of extra admin.

I just want affiliate to block all registrations like 'secure invites' does. (it blocks wp-signup.php and buddypress register pages too unless invited.) The trouble is, if i run this plugin and then want to run affiliate a new user would click the affiliate link then have to use the secure invite link...

Question: if affiliate uses cookies, would secure invite still work?

This would also stop spammer/spusers/sploggers and all that.

And i check the search, the last wpmudev invites topic was from 2 years ago...?

Thanks

Johnny
