xtable in Sweave works awesome, but does one table per regression. You can feed it a data frame, too, so I have been manually rbinding
Check out the apsrtable table package in CRAN Which creates American Political Science Review style tables which look roughly like what I think you want. It takes lm and glm models as well some non-linear models from some packages. It also has a long series of options for generating stars at particular levels and such. There's a nice vingette and it generates both LaTeX and HTML tables which can then be added to OpenOffice/Word.
I've been using it for 2-3 years now and it continues to be under active development. I've just looked quickly but it seems much more solid/featureful than outreg.
