Remote User Location Capture Website

Creation of a secure website that enables remote employee's to enter their physical work space location into a form and also upload the data result from the user running an "arp -a" command. Specifically need to write remote command code to have a windows or mac PC user run an "arp -a" command to enable the resulting network info to be captured. It is OK that users would need to initiate the arp -a info capture process, but it needs to be a "click-button" experience for user to avoid confusion (they shouldn't need to type in the literal commands, and copy to response text, paste it, etc.). In the end user will manually fill out the location information form (street, city, room, floor) and click a button to allow website to capture and upload the "arp -a" network path information. (if this can be remotely executed and captured that's even better but I believe internet firewalls will prevent that). Goal is to create a database with that captures this collective record information outlined above for each user who log's into the site.
