The catch of course is that then you have a collection of files on
your Linux box that are pretty much useless since your can't mount
them or read the contents in any meaningful way. If you're running
a Linux server as the destination the easiest solution is to create
a virtual machine running the same revision of OpenSolaris as the
server and use that as a destination.
It doesn't necessarily need a publicly exposed IP address - you can
get the source to send the differential file to the Linux box and
then have the VM "import" the file using a recv command to
integrate the contents into a local ZFS filesystem. I think that
VirtualBox lets you access shared folders so you could write a
script to check for new files and then use the recv command to
process them.
VirtualBox can forward a host port to a guest, so one can ssh from
outside and process the stream directly. Also note Erik's public key
idea below.

The trick as always for this kind of thing is determining that the
file is complete before attempting to import it.
There's some good examples in the ZFS Administration Guide (p187)
for handling remote transfers.
zfs send tank/ci...@today | ssh newsys zfs recv sandbox/res...@today
For a staged approach you could pipe the output to a compressed
file and send that over to the Linux box.
Combined with a key exchange between the two systems you don't need
to keep passwords in your scripts either.
Cheers,
Erik

The ZFS send/receive command can presumably only send the
filesystem to another OpenSolaris OS right? Is there anyone way
to send it to a normal Linux distribution (ext3)?
