I'm also getting terrible speeds,About 1/4 of my advertised speed..
Hopefully They're routing all the traffic through another network and updrading the one we're on,As I've been told an upgrade will be happening soon!
Also,As far as I know the PermaTel service will be using independant bandwidth aside from your package,Meaning you can be downloading and streaming youtube videos while on the phone(An issue we have with blueface),If this now isn't the case, I wouldn't change as I'd assume the prices will be the same as blueface..It does mean that permanet would need to install the SIP router and therefore you could be waiting a while depending on the popularity.
I am looking forward to seeing the packages and prices though!
