Design a plugin binary API, dynload the plugin. It is not necessary that 
the RTL is shared for this purpose (allthough it could reduce the size).

This way you only have to keep the plugin API backwards compatible, 
and could allow binary plugins to be used with any Lazarus version. 
Keeping a plugin API compatible is very doable, unlike of the full RTL, FCL 
and LCL, which seems next to impossible to me.
