Catalog Manager as a Web application

I cannot understand the reason, why Commerce Server product team did not released any business application as web based tool also....

anyway if you need it and you want to avoid to code it from scratch there are few alternatives:

1) this is a free project on Codeplex using CS 2007 Api
http://catmanweb.codeplex.com/

2) if you have Sharepoint and fancy Silverlight 2.0 you can use the inline product editor web part

3) buy a product called Admin Extender
