the problem i think itsn't that bolehvpn can work with wimax or not. but the cap. once u finish ur data quota, than its usually an isp level cap which means even vpn cannot help to uncap it. I use bolehvpn on Amax Wimax(b4 they were ultimate data usage) with a ridiculous NAT & loadbalancer type combo backbone and keep changing our ip when u visit some new site. It was on wimax and it worked well with wimax. but than again, some isp do block ports that are needed for vpn.
