This is great for small finance startups where previously the costs were astronomical.
I'm certainly going to look at incorporating this in to livelystocks.com which could benefit from some realtime finance data.
I was initially very excited but once you read the details it's the spec and implementation of the API for a realtime market data messaging system that is public and MIT licenced (unlike Bloomberg's competitors) not any actual data sources.
Presumably even if you want to test a new client implementation, you would need to have an account with Bloomberg (the magazine article mentions "beta" markets but I'm guessing that doesn't mean in finance what it means to developers).
I haven't looked at the license yet, but I suspect it may have certain restrictions with regards to providing the data to others without becoming a paying customer.
