Unfortunately the only thing that qualifies is bcprogtool - however the URL that we had in our wiki is gone. Go do a google search (it's TCL/TK software, but beware as it's unsupported...)
The real answer is to get a cheap desktop, load it up with memory and use one of the Windows apps (ARC-XT, FreeScan (which is freeware) or ProScan). There really is very little written specifically for anything beyond Windows...unless you use VMWare or Parallels (I understand that works OK, although I'm very far from a Mac person...)
