Please help guys.
I am interested in this also. Monero guys could probably guide you in this but probably won't if you tell them that you want this for DigitalNote purposes. I could be wrong - it just depends on whether you stumble onto a fluffy or a smooth! You could be economical with the truth and say you want to provide Monero services. Any differences would be trivial. But you would face the wrath of the Monerologists if you got found out!
Also the folks on bytecointalk would probably be more willing to help, knowing that you are a DigitalNote guy, and I would guess that as time moves on the DigitalNote API will resemble that of Bytecoin much more than Monero anyways! Having said that I think the Monero integration community is pretty large - probably second to BTC itself.
