As of 1.6 (and possibly 1.5) you can definitely update through the market. As long as your updated app is signed with the same cert, when it is installed the system will put the new one in /data and ignore the old one in /system.
Be sure you set your version code (versionName is ignored) so that the newer one in market has a higher number; the system also takes care of things like checking if the one in /system has a version code >= the one in /data and deleting the one in /data during boot if that is the case. This allows an OTA update to deliver a newer version of the app and correctly handle things if a market update had been installed.
