You're still paying money with those concerns?? Just move your money (and data) to SpiderOak and be happy: good client-side crypto can be done properly.

you don't know what you're talking about. Openvpn was never affected by the "renegotiation bug" as it doesn't use SSL for that component. As it runs over UDP and TCP, it had to come up with its own way of doing that - hence no problem.
That in combination with HMAC authentication makes it basically immune from that issue anyway...
Actually, can someone explain to me what the real difference is between "master mode" and AdHoc or mesh networks?
Why is it that only a few chipsets can "do" proper full-blown "master mode" (ie be an Access Point), and yet other chipsets can be used as AdHoc or mesh? I mean - what's the fundamental difference? I've been through this with Linux systems and can't understand why I can't just grab any WLAN card, bring up the interface and whack a DHCP server on it - why doesn't that work for them all?
