Thanks for all your replies. I enjoyed even the humorous suggestions. I decided on "hyphenated acronyms", as my collective term. Not because it covers everything in this portfolio, like N-N-N and W-O-R-D, but it covers 90-95%. Good enough. Best of the rest was "hyphen folio" and "hypholio", imho. Although these would have been better served as domain names. Thanks everyone for participating.
