Jim(jbarry-esristaff),
I would like to second Rebecca Strauch, GISP proposal, some sort of lookup page with title and description and then a link to how to request it from ESRI. This seems to be the obvious solution. You clearly have no intention of reinstating the ArcScript site as code sharing site now exists and personally I'm happy with that. But there was an incredible amount of code on ArcScript and to loose that is a terrible waste and ultimately very unproductive and a negative impact on the GIS community. What about scientific journals that reference extensions on Arcscripts, people have no way of following up that research if they cannot obtain the extension/model? To say it's all there and accessible to ESRI staff is kind of good to hear but useless to the REST OF WORLD!
I remember whilst ArcScript was still alive a couple of years ago, discovering someones AML code (yes AML!) which I was able to review and ultimately convert into ArcObjects.
In my eyes there is a desperate need for some sort of web page that can be searched, even if it is a one off "dumb" static HTML page. If a particular tool is requested regularly then ESRI could move it to the code sharing website. Otherwise new contribution should be uploaded to code sharing.
