@David...I am well aware that what I set out to do is technically feasible but it has transactional limits...hence why I'm also applying for Paybill at the same time so as to give my company breathing space. I hope you do realize that transactional limits will just get higher and higher, however long it takes. It's your kind of attitude ('dream on' et al) to the idea - and others similar - that makes people complacent...I refuse to sit and be satisfied with the status quo. So what if I try and fail? At least I will confirm what is and isn't possible, technical or otherwise. Tinkering and trying out new ideas is not new to me, it's how I have paid for my education and bills years out of campus. It's my money and time that I spend on this endeavour for the sake of informing others (and easing my business when it works), not yours...
