Just be aware that StarOffice was known to produce horrible EPS basically unimportable to anything else (including LyX). Don't know how the situation is with OpenOffice.
Matej, thanks for the warning! Indeed, the EPS file is not importable from OpenOffice into LyX, as the bounding box is not specified. However, I can use the PDF or JPG format and produce a PDF output LyX file instead of a DVI one.
