I am working hard on adding a REST interface to the VSCP daemon this week. Formats supported are plain text, CSV, XML, JSON and JSONP  and you can send event/read events/write variables/read variables and read tabular data. I personally prefer the old tcp/ip interface but I know many will like this interface better. Also from this version SSL will be available as an alternative to the web/rest/websocket/tcp/ip interfaces in addition to the password and remote machine validation mechanism previously available. Making this the most secure solution available.
