Is there any equivalent to the SPP profile from Bluetooth Classic? I've always used this as a way to transmit custom data using Bluetooth, but I can't seem to find anything equivalent for BLE.

Unfortunately no ETA, but for an actual working example of a custom service you can take a look at the UART application available here: https://devzone.nordicsemi.com/index.php/nrf-uart-app#reply-402

Sorry for the delay in answering this. Unfortunately no news on the schedule for the app note.
As for your questions on host support, Henning, they may be better suited in a separate question. It won't be covered by the app-note. However, to answer it briefly most new OS-es from now seems to expose native GATT APIs, making it easy to connect to BLE devices and using their services. It won't give you a normal serial port, but APIs that still should be quite easy to use. This is applicable for Windows 8, iOS from version 5 and Android from 4.3.
The application note is now out! Get it here: https://www.nordicsemi.com/eng/nordic/download_resource/24020/2/80193304
Just for completeness, the application note mentioned is available here: https://www.nordicsemi.com/eng/content/download/34055/573345/file/nAN-36.zip
