It would help for sure.

While, by far, not being the cleanest solution, you could also send in 
your registration VLAN gratuitous ARP packets (for the IP address of 
your PacketFence in that VLAN) very often - so even if some computers 
get the wrong ARP table entry, it'll get poisoned pretty quickly back to 
the correct value, enough to get the users through the registration process.

After all, that's pretty much how was working the previous ARP-based 
isolation code.
