It shouldn't be hard to port JFFS2, and its licence should permit that
as long as your changes to JFFS2 itself are released. 

The MTD code, however, is purely GPL and cannot be distributed in a BSD
kernel unless the whole kernel is also released under the GPL. You'd do
better to find your flash drivers elsewhere.

For porting JFFS2, look at the current code in CVS. It's already running
on both eCos and Linux, and I've even heard that someone ported it to
Windows.

The thread is optional; eCos doesn't use it. But it could easily do so.

They are different. Which is more suitable is dependent entirely on your
application.
