....but, if you must have one...
A remote is little more than a hose. They should have the same 1/8" NPT thread as quick-connect fittings and steel-braided hoses and macro fittings. The main difference is length.
I recommend getting some sort of valve to put between the end of the hose and the marker. You will want to set your marker down sooner or later, and it isn't always convenient to remove your harness when you do so. I am especially fond of the Pro-connect fitting. It takes the place of the quick disconnect parts (both the male and the female) and works in a similar manner. The difference is that when you want to disconnect the female (hose) end from the male (marker) end, you push in a button on the side of the female end. This releases the male fitting, but holds the air pressure in the hose. Degassing the hose will cost you a lot of air, which may be harder to come by if you switch to HPA.
If you try to remove your marker from the hose with only a quick disconnect without degassing the hose, it will whip around and vent your tank as fast as it can flow.
On a related note, if you are using a long enough hose section, you are less likely to siphon liquid CO2 into your marker with the remote set-up. Most remotes keep the bottle upright (that is, pin-valve up) in your harness, which makes siphoning less likely. CO2 will still contract and expand more than HPA, however, so velocity consistency will not be improved just by using that remote.
Jahlad is right, you are almost certainly going to end up switching to a bottom line drop-forward. Being able to brace a marker against your shoulder makes it so much easier to hit what you want to.
On the other hand, the guy who got me into paintball in the first place has been using a remote for the last several years. He plays a lot of scenario, 24-hour type stuff and claims that his arm gets less tired if he doesn't carry a tank at the end of it.
