Running on our Servers:
You can rent the Server month-to-month from Sonic (www.sonic.net)
Smaller implementations may share a Server, in a totally segregated partition, for a very modest monthly cost.
We provide the WorkMovr software, Linux, MySQL Database Software, the XML Parser and the Image Viewing software at no cost to you.
You just need regular desktop computers at your office, and a fast Internet connection - DSL or office LAN for example. Our programs are set up for 1024 x 768 resolution (typical standard) and 17" or larger monitors are desirable.
Groove installations need to provide their own Groove licenses for their desktop workstations.  Groove users may connect through lower quality connections.

Running on your Servers:
We provide the WorkMovr software. 
You will need to provide the Server, the Operating System (e.g. Linux or Windows Server), the Database Software (e.g. MySQL or Microsoft SQL Server) and potentially the Image Viewing software, depending on your installation requirements.
Non Linux/MySQL installations will take a little extra time to configure.
In computer science terms, WorkMovr is a low transaction volume system, as we are usually waiting for individuals to perform tasks.  These tasks often require some thought, so a per-workstation transaction rate may just be 1 every 5 minutes.  So your Server may be modest in size.
