ACARS is often used for LS (BA have been using it for years). When looking at an ACARS Loadsheet you woulden't understand a thing of it, unless you also knew a regular loadsheet.
The same goes for weatherreports. You can send METARs or TAFs to ACs who are beyond a VOLMET, but to understand these, you need to know how to decipher a weatherreport.
Widely used for departuremessages - but those are very easy to read, even for a "non-ailiener".
Hope this helps
