[squid-users] delay pools help

Hi,
Since we are in a isolated area there are no ISP to offer permanent
oconnections. One software company some distance from us have agreed to
share their bandwidth with us for2 months. They will give us 128KBps. But the
charges will be very high per Mb. So, I want to allow only few IPs
(192.168.1.1 and 192.168.1.11) full use of bandwidth, the rest should
use only 64 KBps. I read FAQs and config files on using delay pools, but
cannot get the hang of it yet. Can somone hint at some clues for this
particular thing?

Thanks in advance.
With warm regards,
-Payal
