In your scenario, you will have to be creative and use one of your travelers to carry power back to the remote. Depending on the remote that you have (with LED or without) you would need to follow the correct diagram below;
If you have 2 wires between both locations (line and load) -basically what is typical of a 3-way, you have enough wires to make this setup work. (the diagram on the right requires a nuetral at the line location)
Don't think of it as you would a mechanical 3-way, just use the traveler wires to carry the hot or communication signal (YL/RD terminals).
