Any free rapidshare tools to download a series of rapidshare files for free use?

Like many of you, even I am a free RS user, I wanted a tool which can help me download a series of files continuously - I want such a tool which can bypass all rapidshare limits like changing ip / proxy, bypassing time delay of countdown etc. Can anyone help me with a tool which can download automatically multiple rapidshare files.

Main thing I want is to download rapidshare files overnight. I don't have any problem to keep my PC on all the night, but it should a complete set of files say a few GBs.

Note: I have dynamic ip and hence disconnecting and reconnecting to internet changes the ip and the tool you recommend may just disconnect and reconnect before starting the new download.

Hoping for valid reply. Thanks in advance.
