Display Package version number in HTML?

Hi,

My customer wants to display the version number of the apps/xx package in the HTML.

I'm just wondering if this is a good idea, i.e. the actual package contents could be overwritten, but the package doesn't change.

Also - how could that be achieved?  There is a services JSP in the CRX package manager - could that be used?

Thanks!
