I have run several hardware/software shops and for me the only rational
arguement for source code is "what will I as a user do if the company goes
"belly up" or stops supporting the product. The only pragmatic solution
that I was able to work out was an escrow arrangement whereby the
developer placed the most current version of source code and documentation
with a third party (e.g. a bank). The developer owned that source code
and I was not allowed to access it unless the developer either stopped
doing business, stopped supporting the software, or failed to meet stated
obligations (e.g. failed to fix a major bug in some reasonable time). I
have negotiated several of these agreements and not once have I had to
exercise the escrow agreement and gain access to the software; however,
the existance of such an agreement gave my company peace of mind.
