And there is similar news on Tech Crunch.
Well my English has grammatical mistakes but it seems like my idea doesn't have that much issue. Yammer has announced what i had said in my posting ( point 2 - 2. If any organization wants to deploy netvorx within their network rather than using http://www.netvorx.com then we will charge for maint & support. If organization wants to just use as-is version then there won't be any charge.)
lets see whether today's Yammer annocement has any relation with Hacker News Posting or my email to TechCrunch just before Yammers annoucement ... :)
In either case I am feeling better that my brain is still working in right direction to generate idea
