Just curious as to the purpose and reasoning behind this requirement. Thanks.
Sharing gas is much nicer when the divers can keep some distance between them. The long hose is required in an environment in which the divers must exit single file while sharing gas.
OP
That confirms my uneducated assumption that it is specific to cave and wreck penetration diving with an emphasis on caves.
Agreed! Although the essence of recreational diving is that the surface is always an option, it is not always the BEST option, especially if one is diving in an area where there is boat traffic, or where the only good entry is a limited spot. In that case, if you have a diver low on or out of air, it is awfully pleasant to be able to share gas and swim comfortably, side by side, to a better place to end the dive.

Meh, why do any research to find out why, when its easier to fire off a question on scubaboard and summarily dismiss it as "only for cave divers." The explanation and reasoning is a link right next to the gen equipment link. Reminds me of the silly thread about "why dont dir divers use a computer." Not willing to spend 5 minutes to read an easily accessible website, then perhaps being proficient as a diver isnt your thing either--or maybe its just reading isnt your thing.
OP
I did. I went here: http://www.scubaboard.com/forums/dir/44823-what-dir.html then I went here: Equipment Configuration | Global Underwater Explorers I learned something while I was at those pages.

No need to be insulting. The OP's assumption was not off the mark. While the long hose configuration is now widely used for open water diving (by those that use them that is), it was originally designed for air sharing in restricted environments.
