I'm not sure I'd recommend this, and I don't know anyone 
who uses such an approach.  Sitting any cyclamen in a pot 
in a saucer permanently filled with water is a recipe for 
rot, especially whilst dormant in the summer.  With the 
exception of C. graecum and maybe persicum, cyclamen have 
pretty pathetic root systems that will rapidly rot if too 
wet when dormant (or even when in growth).  They hate 
being over-potted, with a lot of unused or stagnant 
compost around them.  It has been hypothesized that C. 
graecum likes to have some moisture at the roots whilst 
dormant and this improves flowering.  After playing around 
with this for several years in several ways I've not been 
able to see a consistent correlation, and I know for 
certain that too damp will be disastrous.  Last year my 
hundreds of graecum flowered quite the best ever and they 
received no water for 3 months.  No cyclamen, except 
possibly rohlfsianum, likes undiluted heat, and over 
desiccation is detrimental.  The tubers with thin skins 
(coum, the repandum complex for example) are very 
susceptible, as is hederifolium, strangely.  Once a tuber 
is wrinkly and shrivelled it can be carefully rehydrated 
but this can lead to rot if it very hot.  I have taken to 
witholding water from all my cyclamen from mid-June to 
mid-September, apart from an occasional quick flicking 
over with a hosepipe if they are quite dry.  I do keep the 
pots in a shaded greenhouse and also put a sheet of 
insulation over the pots of those that most dislike the 
heat.  Cyclamen graecum is like the oncocyclus irises in 
the summer - asleep on top but busy down below - they also 
have deeply delving perennial root systems.  I suspect 
Scoliopus is the same and mine are kept pretty dry on top 
in the summer but never hot and desiccated down below
