- Ah, yes, I guess the IPC stuff would be a sticking point, assuming the
- BBS software used it - that's a problem I've never run into with all
- the various and sundry stuff I've ported. You're absolutely correct
- in saying that Linux is missing a bunch of that sort of stuff -
- whether the BBS stuff needs or not is the issue.

- I didn't mean to refer to such standard things as IPC and file locking
- as 'ugly SCO hacks' - you're putting words in my mouth. I meant more
- along the lines of "do this, then that, because SCO does something
- bizarre and non-standard there". There are just as many ugly Linux
- hacks as SCO ones, I'd imagine. (Summary: I was referring to hacks
- in the application to get around shortcomings in the OS or using
- bizarre/obscure features of the OS, not any particular strangeness
- about the OS in particular.)
