Shareware and Unix?
McDoobie asks: "Is there a market for low cost shareware in the Linux/BSD and Unix market in general? Would it be worthwhile to have a small home based business next to ones regular day job producing well made, but small, shareware for an environment that is dominated either by large corporations or Open Source developers? If so, what should a potential developer/publisher focus on to make their products/price range attractive to customers? What type of customers are most likely to look into such software? SOHO? Small Enterprise? Home users?
In a nutshell, where should one begin when investigating the potential of the Un*x (and perhaps Apple) environment for the small time developer who's interested in earning a few dollars on the side?"
a kind of 'service' company, instead ?
As pointed out, shareware on a free os doesn't sound that great. On the other hand, wouldn't people be ready to pay a small fee for having their database / browser / random application correctly installed & configured ?
Using SSH/Telnet, you can easily hop over that person's box, and do stuff directly. Of course that requires some trust between you & the user, since you'd prolly be able to trash the whole system ^_^
Another suggestion which comes to mind: develop software on-demand, and release the source as Open Source. Like, someone says 'ok, i need a small app that does this thingy, can't find it. i pay you some price, you make it, and release sources under an Open Source license.'
This has the advantage to ensure you do software which'll actually be used (even if by only one user !), and people will less likely be afraid of the 'company goes boum, source lost, money lost' scenario, since sources will be available...
Just me 2 cents of euro...

I think that it will be hard to do. The free-Unix crowd is used to having their cake for free and even if you came up with something unique, some developer would probably create a free clone of it.
Since you mentioned MacOS X, I would suggest developing for them as your primary audience. Offer a version for Unixes as well, provided you can do so without killing yourself, as paying users on those platforms will probably be few.
