Well it looks like we have a whole raft of tools coming out according to this press release . I blogged about the BETA version of the application analyser earlier. If you have a play with it, please take into account that it is BETA software and isn't ready for production use yet.
Just as an update to this, the analyser has a current limit of 1,000 databases per run. I believe this is is due to an issue on Domino 6 Server "Out of Private Handles' message on Domino 6 server reports a maximum of 18171" - More info can be found http://www-1.ibm.com/support/docview.wss?uid=swg21108940
