Looks like we're making progress in that direction ;)

Agreed.
With regard to Windows, unless some Windows programmers step up to do
the work, I don't think we'll ever end up very polished on that
platform. Martin and Stephane have done good work getting it to work
under MinGW and Cygwin, but neither of them are windows users. [We
could be seeing a cultural difference here. Folks from the free
software world understand that software gets written by people, not by
some abstract "company" located someplace else. If the hypothetical
GNU Radio windows users keep waiting for somebody else to do it, it'll
most likely never get done.]

Sounds reasonable. I think I'd consider this the minimum set:
gnuradio-core, gnuradio-examples, gr-audio-<appropriate>, usrp, gr-usrp,
gr-wxgui
regardless of whether they had a usrp or not. I expect that at some
point in the future we'll have a gr-pyqtgui, and then we'll see how the
two GUI options compare.

Seems reasonable.

I'm not aware of anyone currently working on a .rpm distribution.
Ramakrishnan has been generating Debian .debs for the past few years.
I'd love to have .rpms, if somebody is willing to generate and test
the .spec files on say, SuSE 10.*, Fedora Core 5, and perhaps Mandriva
200{6,7}

Actually, I think that most people use emacs, of course ;)
There are a couple of docbook modes to choose from...
I'd definitely stay away from using OpenOffice to generate docbook.
I'm not familiar with Vex, let us know how it works out.

Thanks again for all your input and ideas.
