Yes, but on-rev obviously does connect to said 5.0.1 database. I did  
not confuse the difference, but falsely assumed that this fact is  
clear to you: on-rev scripting is able to connect to mysql 5.0.1.

Note that I do know about lgpl and the differences.

The "touching" is exactly the problem here. Namely what constitutes  
touching, and what not? In my view, making an external wrapper around  
the gpl mysql libraries would mean _for sure_ that said wrapper would  
need to be gpl.

However a rev standalone that _calls_ said wrapper (even when sharing  
data structure) is not obliged to. Thus the link to the wikipedia  
entries subsection, which does mention exactly such a connection is  
disputed, and not yet enforced either way.

I also object to the connection "opensource" = "minefield". the worst  
that could happen would be that runrev would need to _cease_  
distributing the disputed code, basically not supporting, updating and  
shipping the mysql external anymore. Furthermore, although that'd be  
certainly unpleasant, I can't imagine it happening. Why would any open  
source or mysql advocate actually want rev to cease the support of  
mysql?
