I think your best bet is to use tinc in switch mode instead of routing, 
and configure the tinc interface like if you had one big ethernet 
segment connecting all the tinc nodes - and then run you OSPF on it.

(aka have one dedicticated subnet for all the tinc nodes, give each node 
one ip out of it, do not put static routes for your other subnets into 
the tinc config, and let the OSPF daemon add and remove those routes as 
needed)
