Four whoas.  Whoa!  Actually, your average Linksys router can probably support four 
DLS connections bonded together with MLPPP before it pooches out.  And I use 
"bonded" only in the loosest sense -- it's not true bonding, but "bonding" is a 
convenient word for those of us with only a one-propeller beanie.

You purchase (rent?) four DSL lines (either on a regular POTS phone line or on a dry 
loop) for $31.95 x 4, add the MLPPP charge of $4.00 x 4, four DLS modems (Acme 
Telephone in Kitchener has a good price for a Speedtouch 516: $44.95 x 4 at 
http://speedtouch.ca/ ) and connect them all with a Linksys router running 
Tomato/MLPPP from http://fixppp.org .  Now you have up to 20Mbps download / 2.5Mbps 
upload  with an 800 Gbyte/month cap.  Or if you pay $39.95 x 4 for Teksavvy's 
Unlimited service there's no cap.  And you get a static IP with every MLPPP line.

Yes, Teksavvy is not only OK with this, they provide tech support, will sell you a 
pre-configured router and everything.

Teksavvy started offering this unofficially a few years ago, and when it proved 
immensely popular they charged an extra $4.00 per line and made it official, with 
tech support.

In fact, while they were unofficially providing MLPPP they shook a few bugs out of 
their Juniper switches, which had never been exposed to such a  load in real-life 
before.  Juniper has fixed their firmware, and I've experienced rock-solid stability 
from my single-link MLPPP connection.  

Interesting discussions on DLSReports:

and lots more where that came from.
