I think you got the Bitcoin Sourceforge Iran story a bit wrong. The IP blockage does not only affect Bitcoin, but hundreds of thousands of software packages from compression software like 7Zip to ClamAV antivirus and all other non-crypto related opensource software.
Bitcoin is just one example there.
By the way, I think that Bitcoin itself is legal in Austria and Germany. The german regulator Bafin(www.bafin.de) recently explicitly explained that Bitcoins do not fall under the E-Geld law. (Search for bitcoin on their website)
