As was remarked in connection with another topic recently, money isn't the answer, but it helps. Maybe the NetSurf developers should consider a development fund along the lines of Peter Naulls' for Firefox. Or maybe now is the time to consider a modest commercialisation of RO NetSurf, along the following lines. Stage 1: the next stable RO release (3.0?) is offered for a minimum charge of £X, or more if the upgrader feels like supporting the work voluntarily. The resulting income supports the work of future-proofing the RO frontend. Stage 2: RO version 3.01 is then released with the upgraded frontend on the same £X+ basis. The disadvantage of this approach of course is that upgraders to 3.0 only are supporting work the benefit of which they will not receive.
The above flies in the face of NetSurf's voluntary approach; obviously the best outcome would be for a true volunteer to step forward. But this browser is too important to the platform to be allowed to wither without all options being considered IMHO.
(The value of X to be set according to the amount required divided by the expected uptake).
