Security labels in 10.2

All,

I am interested to know customer stories about successfully implementing Windchill security labels in 10.2 or in previous versions.

We are in pre-study stage using this feature.

Little bit background why we are exploring this option.

We see Access control is not enough to fulfill needs.The security labels might enable us sharing data efficiently with third parties,JVs etc. But still wondering what disadvantages and challenges it brings. Other reason behind this study, we would like to have our data classified (IP classification) as Confidential, Internal and Public etc.

Thanks

Ayyappan
