Shadow, you mentioned that you downgraded to 0.3.20... is there still a link available somewhere to download a compiled version of 0.3.20?
I would 100% support a fork for a client that doesn't force transaction fees.
You should be able to select an older version via Github.
Of course, that's source-only.
Also, there are 0.3.20 (and older) binaries on SourceForge.
http://sourceforge.net/projects/bitcoin/files/Bitcoin/The problem with fork is i can only compile it for Linux, somebody else has to compile Windows version.
EDIT:Completely forgot about MacOS.
I am not doing MacOS as well.
