As far as 'sharing' is concerned, I think you will find that there is still a copyright on the EPC, even though I don't see it being offered as a 'product' by XPart or anyone else anymore.
Older MGR copies still floating around, would need installing on a PC, and I believe that getting that to work on anything other than non-current Windows versions (<=XP) and IE version < 9.0 is difficult or even impossible (its not just a matter of changing the computer date/time of day). I acquired mine (MGR, not a copy) some years ago, and is from 2010 (I think). It runs on an old XP machine, which only exists for that purpose!
