No, but some people started (SSRP), really a good starting point...

This is the commercial point of view. I compare this to the Microsoft-approach. 
They need lots of money for producing, testing and supporting
operating systems and Office. You can get similar for free with Linux and 
OpenOffice, both using older abandoned software parts, recycled, collected
from public domain, contributions from companies that want to improve certain 
functions (more cost effective than creating a new operating system from
start) ....

This is commercial thinking. For hobby or student projects you don't ask if 
it's profitable or not. It's just for fun or for educational purpose. The
SSRP receiver board was about $120. So, what's the risk of bankruptcy ?

That's why it is more expensive than my cheap GSM mobile phone, $30 with lots 
of digital/RF electronics included. I think for $100-$300 you could
build a good SDR with mass-market chips (USRP uses quite common chips), 
affordable for students and hobbyists, with certain trade-offs regarding
maximum performance.
