I've been trying to be consistent at calling them the 'datadev' and
'rtdev' (no spaces) so it's more obvious that I'm using a jargon.  But
'rt' makes no sense these days and I never did come up with a good
retcon for it though.

"RelaTive"?  Because the rtdev is "related" to the datadev by metadata?
