1. EFC have a five year groundshare agreed at Ware, do they not? Obviously, I do not know the terms of the agreement and for all I know this could conceivably be a maximum term, like our 10 year deal at Brimmo, such that should the situation demand EFC could leave before the 5 years have expired.
Actually there is of course somewhere in the borough of Ryman standard, but it is not available to EFC - not for 10 years anyway!
But is there any realistic chance of EFC moving back? No, not really, but as you say, who knows. And as I said, such a move would be disatrous for BOTH clubs.
2. Survived is the word. Thanks to the sheer hard work, loyalty, belief and perseverance of a very few staff and fans, EFC have just about survived, as a legal entity. How much longer can this continue is the question, especially with relegation looming? I'm not wishing to put you down for the sake of it, but how does a non-league club playing well outside its home town attract or maintain any support? Gradually your 30-40 die hards will drift away, and there is no-one to replace them.
Personally I can't see how it will work, but as I say, it is of course your problem.
