Take a look at my product Cloakfish:
http://www.blackhatworld.com/blackhat-seo/black-hat-seo-tools/39912-professional-ip-anonymity-tool-cloakfish-anonymity-discussion-thread.html
It is based on the Tor network but it uses a heavily modified private tor client and a commercial controller (Cloakfish).
The servers deliver a list of realtime working tor nodes (the official tor nodes are mostly not working) you select a number of them.
You can select by hostname, tld, GeoIP (USA as example) and speed.
Then you start as many as you like, specify how many hops you want and ready to go. (no more configuration required)
Up to 128 IPs can run at the same time.
If one stops working you'll be prompted to use another one.
It uses
faster routes,
shorter routes and
realtime tests to maintain it.
The benefits of Tor are still there (
untraceable anonymity, e
ncrypted connection) but all the bad sides (instability, low performance, randomness, slow paths) are mostly removed.
Next to the product you receive
professional customer support and
regularly free updates including new features.
I have got a lot of customers atm, as far as I can tell all are satisfied just ask in the thread
