Hello and thanks for the kind words.
I have actually just answered my own question by visiting the Lavalys site which, (as I might have expected if I'd stopped to think), carries a comprehensive 'Features' list making it clear what the different versions of it's programs can, and cannot, do. It looks like the IT pros are out of luck unless they pay!
Lavalys have been offering their Everest program since January so, if it is AIDA under a different name, Fiery would seem to have arranged an overlap period. There is a link to Lavalys at the AIDA website and also to something called 'Motherboard Monitor', a remote admin program and a Hungarian consultancy!
