VTP questions (multiple VTP servers on same domain)

I read

and just want to run this by you guys to see if I understood it.

1. If two switches are set as server with VTP Pruning disabled, no password, empty string as domain name (out of the box config.) whats there to stop someone to bring up a switch and call him self a master of the VTP domain with vtp version 2 enabled? (nothing right?)

1. do i understand it correctly that when I make a vlan pruning- ineligible, it won't be 'learned' by a VTP advertisement even when the config. revision number is higher, in other words, if I have a switch with some prune-ineligible vlans defined, it doesn't matter if some other switch advertises a VTP advertisement with higher config. rev. number, I won't erase those vlans.

2. what the best way to make sure that only set vlans are 'learned' via VTP?

1. if I have multiple VTP servers on same l2 network connected via trunks with different VLANs on each? is that a disaster waiting to happen?
