Yes, whoever's doing the Vigilant site must be a relative or something.
You should be able to use the local server as the point of sale workstation as well. 500-MHz and 256-Megs certainly ought to be more than adequate for the Linux version.
Vigilant has only Canadian payroll and has been in no hurry to implement U.S. payroll because there are so many programs available for that. I know of a Linux timeclock program if you need one.
