The point was actually not so much about .Stex versus .Snw but that
you can integrate all into the LyX GUI: For my import above I get a
menu entry

	File->Import->Sweave

in the LyX GUI whhich probably is appealing to GUI-users. The same
could be done by registering .Snw and modifying the noweb import
filter accordingly.

The same should be done for output, such that one can do

	File->Export->Sweave+PDF

(or whatever you want to call it) directly from within LyX, rather
then saving & renaming as you suggest under "Compilation".

But I'm too much of an Emacs person to really spend time on such
things ... but I'll be happy to collect information and integrate it
into the Sweave manual.

Best,
