Never having done it, my knowledge on line bonding isn't very good Im afraid.
Be is an obvious choice for the ISP based home type consumer
solution.
There are specialist firms aimed at the more business like line bonding but this can work out expensive... and also the sharedband providers.
If you want to try MLPPP.... then an Entanet reseller such as UKFSN springs to mind. Their owner (
Jason) is probably a good contact point on this subject.
Im sure one of their users did a guide on MLPPP linebonding a few years ago, I'll see if I can find the link in a bit.
Depending on what you want to do,
Load Balancing may be another area to look at.
