I couldn't agree more.
There has to be a way of classifying legal context. In law there is no such thing as international, in most places there is no such thing as 'Software Law' and in a few theres no such thing as 'Intellectual Property'.
It doesn't exist.
'Software law' is kind of a redundant notion i.e trying to enforce those little 'I agree to the terms &..' boxes in a lot of countries is a pointless effort to embark on and will do nothing except run up legal fees.
As with all law it's an interpretation based upon historical context, enforceability and so many other factors. As a developer, would I like to see a S.E. site which covers this, absolutely! But I don't think that this is the right classification and I suspect that this proposal is mostly driven by developers and would seem odd to most lawyers who work across jurisdictions. Generally, software is a subset of IP/copyright & patent which can only be applied per-jurisdiction save for where treaties are signed and enforced, each country will choose to interpret that however they decide.
I posted this discussion here which has a feature request which I really hope you can support:
Law broken into classifications/jurisdictions
StackOverflow's pedigree means that a more general 'Legal' site would be heavily weighted to IP/Software law questions, however I think that we should do what S/O did with programming languages. I sometimes answer questions about PHP, CSS, Javascript, HTML5 ActionScript and could probably help a novice with 5 or 6 other languages but I'd certainly say that I specialize in only a few. The same should be the case for law, but here's the rub: we are used to there being an international standard, if I write code in thailand it's going to do the same thing as in France (shut up about charsets ;-).. In law.. forget it, there must be jurisdictions as categories as well as the normal tagging system or else we will have people thinking that U.S. or E.U law somehow has any relevance at all where the poster is from.
