violation of GPLv2 - remedies?

[Abraham Ingersoll]

(This is a bit off topic, but the problem we've encountered is probably 
something other open-source software developers will eventually cross, so 
I'm posting here..)

My questions --

Once a company has violated the GPL (v2), what remedies does the 
copyright holder have? What must a copyright holder do to protect these 
possible remedies, and what can/should a copyright holder do with regard 
to the original violator? 

How drastically does the situation change if the publisher never bothered 
to officially register the copyright with the library of congress?

Besides the obvious experts (such as the FSF in the case of the GPL), are 
there any other good sources for information regarding copyright 
statutes & caselaw, especially in regards to how copyright laws apply to 
copyleft licenses? And does anyone have references to attorneys who 
specialize in copyright law, software and open source licenses? We're in 
need...

Thanks,
