Would recommend it to anyone.

OC your vital part in this threads case 'bonding/fallover' of UNTANGLE is payware Only, and its not clear if they are using OSS in that payware part.

Is it really possible to increase the Internet connection bandwidth?
The answer to this question is not, "yes, absolutely." It depends on what you mean by
increasing the Internet connection bandwidth.
In essence, the Net Balancer distributes requests originating from the LAN by round-robin (weighed) policy over multiple Internet gateways.
In other words, if at a given point in time there is only one LAN user making only one TCP connection (e.g. he executes only one download from the web), his traffic will flow from a single gateway, thus it would not benefit from balanced connections.
Instead, if the LAN is crowded with users, each executing multiple requests at the same time, as a whole, their connections will have access to a higher bandwidth, equal to the sum of the single-access bandwidths.
We then conclude that a single connection may never have more bandwidth than what offered by a single link, while multiple simultaneous connections will, on average, altogether have access to a greater bandwidth, which will stretch to the sum of the bandwidths of all the Internet links being balanced.
On the other hand, VPN aggregation is a different story. In this case, balancing of traffic takes place in Layer 2, thus a bandwidth increase is also available for a single TCP/IP connection.
