While openlancer is built in the spirit of freelancer, we are building a completely new game engine, so the discovery mod COULD run on openlancer, but only after you port it. Of course, since openlancer is planning to support the porting of all sorts of freelancer mods, we will be creating a "porting utility" that will quickly and efficiently convert most any FL mod to an OL mod.
OL doesn't need anything like FLMM, because it has built-in mod management. You would choose your mod from a list of installed mods and it would be automatically and instantly activated. OL doesn't use scripts (at least not for a long time, when we add script support it would be written in Python, most likely), however, so those will all have to be converted to INI changes, and then converted into the database format that openlancer uses. Again, we already have a utility to convert INI to DB, and eventually we'll have an entire mod conversion pack.
When the Arena release is out (0.1.0.0), we'll be looking more into adding mod support.
