Yes and no. I'm not longer a Sun employee, but still involved with Falcon with both a consulting gig and a separate code collaboration agreement.
My primary project is NimbusDB, a database designed from the ground up for the cloud platform. But I'm still involved in Falcon code and meet with the rest of the Falcon team regularly.
The really big difference is that I don't have to participate in interminable conference calls. That in itself makes a job worth quiting.
[The comment above on Maria is also from me. Slashdot was not at all happy that my MySQL email address had disappeared into the ether.]
