if splitting data into multiple packets does not suffice for you, you
might consider mapping whole memory pages from sender to receiver
(which in turn allows to build zero-copy scenarios).

An example for this can be found in l4/pkg/examples/libs/l4re/streammap.

There's furthermore the shmc library in l4/pkg/shmc, which allows you
to use shared-memory ring buffers between programs.

Cheers,
Bjoern
