Well, you need a frame converter that sends it to an IP address/DNS server, and on the receiving side something that receives that packet on a specific port and translates it to a BT command.
I would say the most complicated part would be the TCP/IP stack, and binding/publishing your address, but if you are running something with Embedded Linux it is doable :)

One specific use-case I have in mind is controlling a Chromecast over the internet. So a smartphone should have its bluetooth signal relayed over an IP network. I haven’t found anything that would allow me to do that yet.
