(...) get list of IP addresses from the swarm, match those to users via ISP."
Err no. Just because an IP is in a swarm it doesn't logically follow that someone is infringing. How much information has to be transferred for an infringement to occur?
Piatek et al in "Why My Printer Received a DMCA Takedown Notice" is also instructive.
Further, the issue of whether the person paying the ISP bill is automatically responsible for the infringement (or whether further identification is required) is also largely untested in this country.
But don't waste your time getting another bachelor's degree - go straight to graduate school.
Grad school can be a good option, but it's stupidly expensive.
I paid for my undergrad and two postgrad degrees in political science by working in IT helpdesk and junior sysadmin positions. You sure as hell don't need as CS degree to get a job on a helpdesk, and parlaying helpdesk experience into junior sysadmin jobs has worked for many slashdotters.
When I graduated I found I'd be taking a big pay cut to leave IT, so I stayed. I still have no relevant qualifications, not even vendor certs. Now I'm the youngest person in an in-house IT team... that I run.
I'm glad I studied, and I'm sure the alphabet after my name helped with various promotions, but I'm good at my job because of the things I learnt in helpdesk and sysadmin roles.
