Jürgen, DL8MA, provides a gateway, which sends direct APRS messages to a related DAPNET-pager. This service is up to now experimental and each entry has to be manually edited by Jürgen (he needs your APRS-ID and your aprs.fi-API-key from https://aprs.fi/account/).

Interface to send a message to the APRS-System: http://www.findu.com/cgi-bin/entermsg.cgi
