Googleing around I have found in the past, a number of web sites where various "app_config" are listed for various projects. I would be interested in helping maintain a wiki for something like that.. This would involve coordinating with various project principles to find what is currently being used such as command line arguments to their client apps. Probably not something a single person could do although I am a retired programmer with not much else to do.

I noticed there is a SETI users group who maintain a "secret" BOINC client.

Maybe there is already a group that is doing this?

If so, I would like to hear from them.
