How so? If the host tells the plugin what (sub-)directory to serialise
into, and then what direcotry to serialise out of when it wants to restore
it will work fine. Thats how LASH works.

Its just not that simple. What about plugins that want to save something
special, they wont be able to work with host that want to serialise. If
you provide the mode general mechanism they cna save hatever they want. We
allready havea mechanism to allow plugins to serialise thier state, just
allow it to include whole files and it will work.

But what if the plugins needs a random selection of the files its loaded
(eg. a sampler)?

LASH works fine. Its working at one level up (applictions within a
session), but the principle is the same.
