WiTopia - Is it safe?

I read a recent articles on protecting yourself from firesheep (a mozilla plugin that meant for good but becoming as a tool for hackers). Read the articles here.

The author that link the articles to another articles he wrote at blog.techrepublic.Here he explains on how WiTopia could provide a secure tunnel between the client and the server that the client wish to connect to or communicate with.

However, the author do forget something here. TRUST between both parties. The question here is CAN WE TRUST WiTopia to keep all our confidential information, such as username and password? Compare to RIM which provide such services for their blackberry phones whereby all information from the devices (email, etc) were stored in their server located in Canada (and few other places). There was great concern on their security and trustworthiness and few countries has requested that the server shall be allocated at their country rather than outside.

So can we trust WiTopia to keep our secret? Is WiTopia safe from being attack or hack? How can we ensure that? Since WiTopia will decrypt our request, relay to the requested site/server, get the response, and relay back in encrypted format to us. It may be secure between client and WiTopia server, but beyond that is no longer secure. That in terms of Trust.

What about Privacy? Shall we trust the service provider with all our privacy data being decrypted and can be seen in the server? How WiTopia protect our secrecy and privacy? Will there be possibility of leakage or it is fully protected even the WiTopia developers or system administrator don't know what is happening (which is impossible for him if in the event he need to do some tracing or maintenance or bugs fixing)?

This are great concern before you proceed with the advice of the author. I'm not saying that using WiTopia is not helping you securing yourself from using wireless devices, but please do get the information on how WiTopia works completely before making such decision.
