Inktomi <URL:http://www.inktomi.com> has announced their intention to offer transparency but they are not an appliance (like Cisco, Vixie, and NetApp) and last I heard they were waiting on some Solaris kernel changes before they could actually ship transparency.

Paul Vixie gave a nice summary of some of the cache solutions available. To be absolutely correct, Inktomi's Traffic Server network cache does very much ship with integrated transparency today! It also provides a bunch of cache services that people like including multicast clustering, HSRP-derived failover, centralized management, adaptive networking and a fast raw-disk object store. We have some info on Inktomi's home page (www.inktomi.com) if you are curious. Paul
