'Permalink' might be more obvious a think to click for those that know 
what it is, but for most users, they are just looking at an internet 
page and don't know or care about this Ajaxy stuff, nor should they have 
to. It's a hack to overcome limitations of browsers working with Ajax; 
no doubt they will catch up in due course.

As previous conversations have discussed at length, the URL should 
reflect changes as you pan/zoom etc. This requires the use of psuedo 
named anchors and iframes instead of a query portion of the URL. There's 
lots of information out there on the internet on how to achieve this.
