I've used witopia for FOUR years and it has only gotten better and better!
at first it was just SSL, then SSL with PPTP, and now:
SSL+PPTP with excellent mac and windows versions, and servers all over the world!
I have managed to get security at any place I've been, and tunnel all my communications without any blocking or media restrictions. As a US resident, I've also been able to go abroad and still use my US-only media services.
Witopia's prices have gone up somewhat over the years, but the level of service has increased dramatically. With servers around almost every major metropolitan area, latency is wonderfully low.
