Custom live tracking to follow friends on Locus Map

Hello,

With official Locus Map live tracking service, some data are return by the server to display friends locations in a group.

Can I return some JSON/Data format from my custom live tracking server to display in Locus Map some position that come from the server?

If not, that woud be a great thing to do, because with a custom service, I could follow my friends who share their live tracking with different servers (Garmin, livetrack24, etc.) by creating a service to collect all the positions and return all of them through a Locus Map custom live tracking server response.
