The PS3 Devs have their own chatroom (which also includes several PS2Dev people too). I am sure they will be happy to share their findings and exchange info/ideas with you as most isn't published on the Forums here... the best way to join them would be to message CJPC, hacked2123, or NDT in IRC EFnet #PS3News and they will direct you to a private chatroom they all hang out in.
In case you are not sure how to get to IRC EFnet #PS3News, you can by using the chat client available at http://www.mirc.com and connecting with any EFnet
server. Then in your status window just type /join #PS3News
and press enter.
Please keep in mind they are from all over the world (some US, some EU, etc) so they may not respond if you message them right away... so if you idle they will message you when they can, or hopefully one of them will reply here.
