This is already how lv2 presets work.

I think ardour saves session presets in the session directory (I can be 
wrong), but any lv2 preset saved in LV2_PATH will be visible by all hosts.
If you save a preset with, say, jalv, other lv2 hosts will see that 
preset next time they startup.
The presets are portable across machines and architectures too (unless 
they contain local paths, but that would be an issue in the plugin not 
the host)
