A YES vote will require considerable constitutional negotiations with UK government over the finer details (aka - everything). With a UK election currently planned for 2015, time taken over the independence campaign itself together with the time required to finalise independence will be pushed well into the future. The current UK government has no mandate to hold office a longer period and is unlikely to go for the other option of an early election (2014). Leaving the final details until after the next election will further muddy the waters as to what is and what is not included/excluded from an independent Scotland such that the tussle may run on for some years. This is in addition to Scotland's efforts to negotiate EU-hood, NATO-hood, financial integirty, government integrity and support for basic social services and health.
A NO vote will require a similar amount of time to negotiate devo-max-max powers which for the same reasons (2015 UK election) be put on a back burner. When the dust settles after that election the devo-max-max will be far from a done deal and will in fact be nothing more than a distant memory of a government which structurally no longer exists and more crucially, will have no legal standing in the then current UK government even if (unlikely) the constituents are identical. Scotland will get shafted and be hived off what appear to be morsels of appeasement but are in fact a load off for Westminster. SNP will effectively cease to exist as a mainstream party.
Aye lads, Bannockburn all over again. Another victory for Scotland whichever way you look at it, but, it just doesn't feel like it, ever.
