I think the BBK race software
http://www.bbksoftware.com/ just spits out a standard file.
To back this up, there seems a very standard format to these results which looks the same on these two sites which are independant of each other.

and
www.results.
trcc.org.uk
Most clubs have chosen the solution of a separate results site, I guess for simplicity. Also it means one person can own maintaining the results, and the other person can own maintaining a club site.
To set up a simple results site like the links above doesn't have to go through committee, come armed with a memory stick and go for it, is what I say.
