Well, a friend of mine is on Sify and his Bearshare stopped working suddenly one day. We tried edonkey, bearshare and emule and they did not work. Shareaza however did work but couldnt connect to gnutella1 (connected to gnutella2 and edonkey though). He told me the day unlimited package (which is on a shared line) had that restriction and the Sify download limited or time limited package and one 10pm to 9am unlimited package have full p2p access.
