Ya, the server client isn't going to be distributed, and the user side won't be until it's completed mainly due to lamers who constantly steal the hard work and credit of the resident PS3 Devs here.
We also don't allow e-mails in threads... that is what Profiles are for, however, if you seriously feel you can be of help your best bet is what I've told numerous others here:
on IRC EFNet #PS3News and he will talk with you awhile. If he feels you are a good fit for the team, he will invite you into the private Dev room where you can discuss things futher. This process is necessary to weed out all of the lamers just trying to join to acquire our stuff, when they have absolutely no legitimate Dev skills.
