BD-Live, is it safe?

[zor]

With the PS3, connecting to the internet, I'm guessing, can put your system in danger since there's some kind of OS on the system ... I mean if it was completely safe, then the PS3 wouldn't include the Internet security software install option, would it? But what about stand alone BD-Live players (I don't have such a beast at the moment, but I thought this would be a good discussion all the same)? I mean could connecting such a stand alone player to the internet infect the player with some kind of malware? Could it mess up the firmware or even brick it? Another thing that concerns me about connecting to the internet is that there was all this talk about the potential for disabling players or something like that remotely if something or other had been cracked ... any1 know what I'm talking about or am I getting it confused with HTPC graphics cards? ... maybe I am because I do remember some talk about it being possible to have your graphics card disabled remotely until an update was released if someone had cracked something or other in relation to it.

And ... what is the point of BD-Live anyway? I mean, you can download trailers through it, but you can download those anyway through your PC right? What could BD-Live offer that your PC doesn't? I'm much more keen on Bonus View features -- I hope that doesn't get neglected.
