Centralized update for third party apps I kind of hate it when applications, which I start, at first search for updates. It's not the updates. Well I fire up an app because I want / need to use it (now). I liked the centralized, system wide update which Linux offered. And SoftwareUpdate just checks Apples software.

Is there a way to centralize the updates of the third party applications?

So far I know about Macports and Fink which update quiet like Linux, but I also use e. g. iTerm, Transmission etc. which would still be left out.

I also heard little about Appcasting, which uses RSS to announce updates, and which is used by some apps I use, but I don't know any URLs.
I use AppFresh. It's nearly perfect. A lot of apps are recognized, even new ones and widgets and prefpanes too.

It's backed up by iusethis to check for update, but can also check for Apple or Microsoft Office updates.
