sbc,
I'm know very little about Brother software itself, but I'm fairly confident that you can share the printer from a machine(XP/Vista/W7) that has it installed to other users on the network. A limitation will be the shared printer will only work for clients that have their drivers loaded on the sharing machine.
Everyone has their own methods and priorities, but I'd suggest that even at what the Govt pays for your time per hour, you probably could have installed UpDox and paid for their fax service (and included patient portal) for a year.
At the end of the day, YMMV.
