If you know where it would be good because we keep hearing things like
that, and we would like to correct them.

eCos is unrelated to Linux. The only link between them is the EL/IX
compatibility levels ( http://sources.redhat.com/elix/ ) to allow *API*
level compatiblity between full-blown Linux and smaller operating systems,
e.g. eCos, uClinux, etc. by subsetting the API.

It very much depends on the application you want to use. ucLinux is closer
to the Linux API, although a lot of that depends on the C library used.
eCos is more flexible, and configurable and has the potential to be much
smaller. There's probably more device driver support for ucLinux than is in
eCos. I'm not a uclinux expert though :-).
