I was impressed with many aspects of ShortUrl. One of those aspects is that SharePoint ShortUrl is written as SharePoint software, and it stores all the ShortUrls as items in a SharePoint list.
We are now using ShortUrl in public production farm and it does exactly what it promises. Well worth the investment.
Cirrus Soft has provided us with a very useful product. The flexibility of the product is observed in several key areas and the support from the supplier has been outstanding.
We have just recently installed the tool in our Production SharePoint Internet environment and our users have provided nothing but positive feedback.
