As others pointed out xdg-open will do that.
You might take a look at my BrowserDetection unit, which uses xdg-open
if available, or tries some other options if it is not there. AFAICT
it should also run under Darwin (MacOSX).
It's at: http://home.tiscali.nl/~knmg0017/software/fpc_laz/browserdetection.tgz

Comments are welcome.

It should be easy to expand this for email use also.
