Well, the plugins could simply share the variable that stores the
preference. Basically: make the variable not 'static' (so it is visible
to other modules), put it in a header file (properly 'extern'd), and
have both plugins include the header file and use the variable.
For an example, see the mtp3_standard preference in packet-mtp3.{h,c}.
Note: I know this works for regular dissectors but I don't know if the
rules are different for plugins--especially on Windows.
