Hello Dan,

that is certainly possible, you would just combine serialize and
call-with-output-string to obtain data you can copy into a shared buffer
and call-with-input-string plus deserialize to extract the stored value
on the receiving side.

However, shared memory between processes or threads on the same machine
has the advantage that one can place data in native formats in there
without having to care about endianness issues etc. So perhaps
object-evict and friends would be more efficient in this case.

The protobuf serialization could be quite useful for distributed
computing applications. Combining serialization of thunks with network
transport and some cryptographic authentication scheme yields you could
quickly construct a secure remote compute job submission server or a
distributed map reduce network, for example.

Ciao,
Thomas
