An idea of how to identify Israeli owned software companies

[Terje]

Is there a web service/API out there identifying Israel owned 
software/software companies/web sites/web services? If I am about to buy 
a piece of software, but don't want to support the Israeli economy, it 
would have been handy if I could just poll a web service to get the 
answer. This information should be kept in a database, and be public to 
the world through a very simple xml API, something along these lines:

Request:
<nameOfCompany>Some Company Name</nameOfCompany>

Response:
<isIsraeliOwned>true</isIsraeliOwned>

Here's one source for this kind of information (I am sure there are 
plenty others):

Of course, a web service like this would be equally useful to those who 
want to support Israeli companies.
