I am using a centralised banning sync plugin that uses an sql database,  so if you ban someone in one of your servers,  it blocks access to all your other servers.  This works well ( except for having to unban via the sql database as unbanid  42342blah   does not work, but thats no big deal as its a free plugin )

Is there a plugin or can anyone make one that can do similar via sql database but with groups  so that if i give someone vip1 in one server, it grants it in my other servers (  so sets the same level in all my servers )  and if i demote someone it automatically demotes them in all my servers.

thanks

EDIT   

I have attempted the Permission Group Synce  plugin but am getting errors preventing it from working correctly, i am awaiting a reply to a request for help posted,  just wondering if there is anything else in the meantime
