PSI is awfully silent with regards to any new development work concerning these products. I remember that there was a lot more activity when earlier versions were being created & updated. However, since 2.5's release a while back, nothing much is being said here or on PSI's website.
Request for PSI...
Can you publish a product roadmap?
Can you share with us what we should (could) expect in the future?
Is there a future for PSI's products (PM, Barca, etc.)?
Business is business and in these days of rapid innovation, a product can become stale just because no new features are added. I would hate to see PM & Barca become a footnote in some history of technology book (like Signal 9 Solutions' excellent "ConSeal Personal Firewall" product after it was sold to McAfee)
