I would have to disagree here. While I haven't bonded multiple DSLs, I
have done so with numerous other technologies, (ATM, ISDN, Ethernet,
...) and I never had an issue with getting aggregate bandwidth.
Depending on the technology you can do this at Layer 2 (multi-link
trunking or Etherchannel), or at Layer 3 using equal cost routing (OSPF
and BGP can load balance links). Going to 2 different ISPs may be
difficult (due to the route for the return path mainly) but provided
your ISP is cooperative, load balancing to a single ISP shouldn't be an
issue. You would fully realise the available bandwidth if this is setup
correctly.
I think we will all cheer, if we see more deregulation of the local loop
through proper corporatisation (either that or the government gets
serious about Telstra offering a *public* service.
