Actually, a rebreather is a bit of an overkill for a sub.  All you really
need is O2 flowing through a flow meter at the proper rate and then 
circulate
the cabin air through a CO2 scrubber which is nothing but a canister of
Sof-no-lime (Soda lime) to remove the CO2.  The hoses, counterlung, etc
of a rebreather are totally unnecessary.  Actually, for submersion times 
of less than an hour, you could probably get by with nothing at all.
On Kiteridge's early subs, he had no life support system, he just surfaced
periodically and popped the hatch to refresh the air in the sub!
