    Looks alright to me, I would suggest starting VLAN5 at .62 if there is any chance of a larger wifi deployment which will give you a little extra space to be able to extend the wireless segment in future without having to move the other subnets or make the address space non continuous for Wireless.

    Hmmmm you have a point about VLAN 4 I may increase that to 1022 hosts also may look like overkill but as you say room for growth seeing as I have just added another 3 Thin AP's and plan to launch public wireless access.
