also static ip helps ensure lesser waiting times on link-removed [/b]
It's quite the opposite actually. Rapishare (free downloads) places restrictions on usage by detecting the users ip and enforcing wait times between downloads and disallowing concurrent downloads from the same ip. So if u have a static ip, you'll be forced to wait an hour or so between downloads whereas with a dynamic ip you can simply power cycle the modem to get a new ip and continue downloading.
As regards speeds in South Delhi, well it depends on what plan you opt for:
Home 699 (upto 128kbps) - 12-14kBps (Day) / 23-26kBps (Night)
Home 999 (upto 256kbps) - 22-27kBps (Day) / 50-55kBps (Night)
Speeds are doubled at night (10:50pm-6:50am) for the above plans; both of which come with unlimited data transfer. Upload speeds are around the same, except they're not doubled at night for the Home 999 plan if am not mistaken.
