Like so many of the issues Wasps are facing, where to play is tied up in RFU/PRL agreements, "guidelines" etc. If all parties are willing to be flexible pretty much every obstacle can be resolved, which probably means they'll be a whole host of sticking points non of which can be sorted out!
Hopefully the Wasps Legends have enough cash not only to buy the club, inject working capital and hire decent players but also get a decent legal team on the case asap.
