Having a driver ready (and internally tested without a public release)
would be a good preparation for 2027.

BTW: 2 of the relevant patents have been filed 2009-02-20:

Hash based file name lookup:

Contiguous file allocation:

IIUC, these would not expire before 2029?

I'm not convinced that hosting in Europe would be safe, but I do remember
that the patented IDEA crypto code had been imported, but was not built
unless a non-standard build option was used.
