Nice post 
- I didn’t think to search for MaidSafe here… doh!
If the proxy ran on the client that would be ok, sortof, but having it on a server defeats the security and anonymity provided by SAFE. We’d have to call it an unSAFE proxy 
It would also not be easy to implement, because the proxy would have to be a SAFE node logged in as the user, exposing his SAFE credentials as well. Reallly not good. A browser based solution that keeps the SAFE client and user credentials on the client machine is best I think.
