Bonded ADSL at 5km from exchange

At 4.8km by line from the exchange, I'm out of range for the 1M
service, so am considering using the bonded ADSL service offered by
Nildram to bond two 512K lines. Will bonding work ok at this distance
from the exchange? Does anyone have speed test results?

Maybe BT will increase the range of the 1M service, but then maybe
I'll want to bond two 1M lines.

Because semirural areas far from the exchange will be the least
economic for BT to eventually fibre, bonded would seem our only hope
of higher bandwidth for the next few years.

What is the attitude of BT to bonding? Are they for it because they
sell an extra service, or against it because it uses up spare pairs?
Could the bonded service be provided at telco rather than ISP level,
so a uniform service is available to consumers? I would suppose that
a small sub £100 box could be developed to perform the bonding in
place of the ~£500 per line Cisco kit. Bonding with USB modems and a
cut down Linux box has been described in this group.

Does the wire into the house being 6-core mean you could bond up to 3
lines without new wring?

Bonding is irrelevant to distance, it's just two 512 lines joined at
the ISP end.

It could, but it isn't.
BT could do many interesting things technically.

It depends on the external wiring.
There may be a shortage of pairs further upstream.
BT have no obligation to provide you as many lines as you want at a
nominal charge, just one.
IF expense would be involved in providing the second or third copper
pair back to the exchange, you might be looking at paying it.
