I posted to grass bug #73 what I should have posted here, (how to deal with nodata is a common pain apparently)
http://trac.osgeo.org/grass/ticket/73#comment:47 * 999 is dangerous, it can easily be an elevation value. -9999 is bad too, you just hit it less often (data doesn't have to be elevation in meters). But even though you hit it less often doesn't mean it's still not going to bite you one day, so it's a bug. but alas, probably for r.out.arc we are stuck with what Arc allows for input values.
