I am having some ideas in my mind regarding obtaining Maximum possible anonimization by ip-spoofing along with chaining vpn connections for the maximum possible anonimization by exploiting the lack of ingress,egress filtering by the ISP's
,but i can not able to find any useful resources for studying,understanding and practical implementation of these concepts So decided to ask here,
I have the following questions
1)Is it possible to chain the vpn connections like we do for proxy?
if yes ,Then to be honest i don't know about chaining multiple vpn's together ,Will it work with out issues?
2)Also most of us know that Internet routers cares only about the destination address not the source adress,it will also one of the greater advantage to us for anonimization

I am not only looking to spoof my internet IP address to some random address ,i am much concerned about getting responses or packets back from the target with my spoofed ip,with out the connection or packets going to the "original" ip i have been using for spoofing ...
in simple i want to you address as my source address and communicate with a third party ,And when the third party sends a reply ,the reply should not be sent to you,it should comes to me...
how to do this?
Also can we use a able to get back replies from the target if we use a spoofed CLASS D OR E address?
I hope this is definitely possible,I had seen some guys using these kind of techniques for anonimization,
But i don't know to do this,but i am very much interested in understanding them theoretically and practically.
3)Next my doubt is regarding hop by hop packet tracing,if we do like the above idea then law enforcing agencies should have do hop by hop packet tracing to trace the real attacker right?,Also i am sure when we do like this it involves atleast 15 hops from various countries for a single vpn ,So if we do the same spoofing technique from multiple VPN connections hosted on multiple VPS servers and chain them together to a single ,will it gives us maximum anonimization?
I do know if we do serious crimes these kind of chains can be traced at any cost,but what if it was an low profile attack scenes like web-site defacements,piracy and e-mail abuse etc?
Just want to know the "truth" regarding real time crime investigations,
I hope many of you guys have seen many similar scenes in your life..
hope some one will help me out...
