NSIS on Linux?

NSIS is Open Source Installer made by the folks of ex Nullsoft. Today I just found "cross nsis" was floating on http://ftp5.gwdg.de/pub/opensuse/repositories/windows:/mingw:/win32/SLE_11/src/ What it means? I would say in near future many cross platform application developers on Linux will able to release Windows installer version on their own independently without touching M$ Windows. Umm probably touch WINE abit more :) though some windowish aspect should to be discussed with windows' user manually.
