Hi Ivan,
As you know, i'm a member of the www.brmlab.cz , recently brmlab installed new software with a touch screen interface.. system is good..i spoke to you a couple of days ago about it...you said your interested..
I think this software would give Divus cafe a better audit with minimm fuss. one of the creators of the software. "pasky" mentioned that he would consider installing the system into the Divus. you can contact him on pasky@ucw.cz
program is open source, so its free.. i'd be happy to pay for the hardware, on the condition that if you did use the software all the time...that you'd pay for the hardware.
alternativly you can work directly with the space.. first best step is drop into the Brmlab and see how the system works.
