I manage the gateway for a large entertainment company you all know and love. All of our users access external content through proxy servers. In our experience, Microsoft's streaming solution provides the best accessibility for users behind corporate proxies. Real-media proxies are few and far between, their own offering fails to support about 45% of their content, and streaming video over SOCKS connections is kludgey at best, and it shows.
It's a shame, but your primary interest is likely to be allowing the highest percentage of clients to view your content with as few interruptions as possible. Currently, Microsoft's ASFs fit that bill. I hate them as much as the next guy, spend as much time as possible away from Windows, but unless your target market is slashdotters and the like, you will get the best performance and success rates from the MS offering.
